Lost River is in recovery from a devastating fire that nearly took the lives of some of their best firefighters and local farmers.

Perry struggles to come to terms with the loss of his home, while Lill and his daughter Taz rival for his attention.

Meanwhile tension mounts between Joey and Fifi over Fifi’s actions concerning their baby.

Luisa learns that her secret love affair with the local cop Mike, is no longer a secret. It all comes to a head when Rebekah Sharp turns up and announces that Luisa’s husband Eris was inside a fire truck engulfed by flames. Suddenly Luisa realises that a lot more people know about her affair than she thought. She rushes to be with Eris who is feeling lost and alone.

Backa is trying to deliver on his promise to be “there” for his wife Svettie, but his fire crew has been traumatised and there’s counselling to be done.

Gossip is spreading like wildfire through town about the fire brigade officer Eris Parsons shooting his dog. Eris and his wife Luisa aren’t around to set the record straight, they’ve gone into hiding. Seems like everyone in Lost River has something they’re trying to escape from.

Svettie is trying not to drown in her problems. Her husband’s uncle Jeff is holding the purse strings of her family’s finances and she’s tired of husband Backa not standing up for her. She runs away to a seaside hotel for a night of something she desperately needs; pampering.

While she’s away Backa must juggle his family and work life with the captaincy of the Lost River Rural Fire Brigade and it’s no easy task.

Backa’s younger brother Joey has returned to Lost River for Fifi and their unborn baby. But things aren’t the same anymore and the couple can’t seem to connect. Joey retreats to a caravan in order to figure his life out.

Meanwhile children’s book illustrator Lill is finding it increasingly difficult to reconcile work with the commitments that come with being part of the Lost River community and when her business partner KC arrives from Sydney, Lill realises she can’t escape. But there are other distractions in the form of firefighting and after accompanying Backa to the scene of a potentially dangerous fire Lill is hooked.

In a last bid attempt to save her failing shop and keep her family together Svettie has borrowed a large amount of cash from a loan shark. But she's keeping it a secret from Backa, telling him the sudden injection of funds has come from the sale of some milking machinery stored in their back shed. Now they're on easy street, for a while at least. In a mood to celebrate Backa and Svettie have the best day they've had in months, even years! The day soon heats up toward boiling point. At the Sharp's a lazy summer barbecue descends into chaos. Eldest son Hank has returned to Lost River and he's ready to cause as much trouble as possible - especially for Fifi. Hank can't forgive the fact that his younger sister is now all grown up and responsible and pushes to find the bad girl he farewelled when he went to jail three years ago. When Rolly Patterson arrives mid-party and makes a beeline for Fifi it seems Hank might get to see the old Fifi after all. There are others for Hank to 'play' with too, in the shape of Kieran and his girlfriend Noodle and when Perry's daughter Taz turns up, it's open season... Perry and Lill arrive at the scene to pick up a distraught Taz and it leaves Perry with a sinking feeling. Is he ready to become a parent the second time around? For Lill, one of the core promises of their relationship has been broken.

It's the summer solstice, the longest day of the year, and the fourth anniversary of the death of Jeff's teenage son Damien. It's always been a long day for Jeff and today is no different as he wakes with a feeling of dread and sadness. Things only get worse when Damien's old girlfriend Fifi arrives at the house to present Jeff with Damien's battered old guitar which she's held on to for all this time. Jeff receives the guitar in bad grace and continues to alienate the remaining family he has around him - particularly Joey, who asks Jeff if he can have some cattle he has been promised. Jeff refuses his nephew's request, as always, in an attempt to control his destiny. However, with a little strategic advice and help from older brother Backa, Joey takes back what is rightly his. On a mission from hell, Jeff clashes bitterly with Svettie insisting that young Carter is sent to boarding school instead of the local Fox Cove High. But Svettie is resolute; she wants her son beside her always. Meanwhile Lill is doing her best to avoid her own relationship problems. She abandons her home for the day, seeking a bit of light relief with the Lost River firies, particularly Joey. Perry is also struggling with his relationship and takes his tension out on his P.A.

Perry’s moved into the mudbrick house and Lill is happy about that-or is she? During a drunken phone call with Perry’s ex-wife, Lill realises her relationship may really be over. Then the unravelling starts as her happiness turns and reality starts closing in. Can she live without Perry?

It’s another hot day and a fire has started in the Tuza State forest. Fifi arrives at Firecom, to the chaos of fires already out of control. Conditions aren’t good-it’s expected to reach 41 degrees and the winds are fierce. All the brigades are on standby as Fire Control Officer Bryce Austin works out the strategies needed to overcome the fires before they link up and the wind pushes them towards Fox Cove. Fifi learns that Bryce will do everything he can to save Fox Cove, including putting his own house at risk.

There’s smoke in Lost River but no fire, yet. Backa is at the fire station organising crews. He’s trying to be Captain in every way possible. But there’s pressure coming in from everywhere. He can’t help wondering why local policeman Mike Jones is sniffing around his wife. And there’s a southwesterly change expected which means the fires will close in around Lost River.

Meanwhile Mike is closing in on Svettie and Sharpie’s dope crop. He’s torn between being the cop and living in a small country town where he has become familiar with the residents. It’s a fine line and Mike is still an outsider. But a secret is out about Mike and his world is about to close in on him too.

Lost River’s very existence is threatened in this gripping episode of Fireflies. Fearfully, Backa watches the fire trucks roll in to Lost River. Backa believes that it is less than 24 hours before the fires reach the village, and he expects they’ll come from the west as well as the predicted front to the east.

Not only is the Lost River brigade fractured, but its members also insist on sniping in front of Divisional Commander Donna Bruce. Backa needs Donna to trust his judgement-they have to get out to the fires instead of waiting for more intelligence from Firecom.

Svettie makes an unexpected visit to the station and learns that the fire may reach Deep Creek by nightfall. She alerts Sharpie, who enlists the help of his son Hank, to help harvest their Deep Creek plantation before the fire arrives.

Meanwhile, Lill asks Perry for a truce until the fire has passed, but Perry refuses, accusing her of demanding his support while she destroys their marriage. He insists she has to learn to act on her own.

Backa convinces Donna that the only way he can unite his brigade is to get them out to the fire ground. However, when they confront the raging fire, the flames have spread too far and Backa is forced to fall back to Deep Creek to backburn.

Svettie, cut off from all communication, is in the middle of the area he intends to burn. Kieran, knowing where his father, brother and Svettie are, convinces Lill that they must warn them before they get trapped. When Lill becomes a hero on the fire ground, she realises maybe she’ll be able to survive on her own after all.
