Owl leaves the park in search of a mate and the Weasel family have left to start a new life else where. Plucky and Dash race again, while Trey harasses the other Farthing Wood animals. Meanwhile, Bully and his rats begin to build their numbers.

Water becomes an issue for the Animals of White Deer Park. Shadow and Hurkel arrive at the park only to see that the only water source Trey will allow the animals to drink from has been poisoned. That was the stream that The Great White Stag perished from. Meanwhile outside White Deer Park, Owl encounters a Rook named Moth eaten Rook who wants to talk to her. However Owl flies away with the Rook following her.

The two snakes find their way to Bully's nest after speaking to a rat with a feeling of impending doom. However Bully manages to escape leaving Adder and Sinuous frantically racing through tunnels with overwhelming numbers of rats looking for a way out. Adder reaches the surface but Sinuous turns the wrong way and ends up trapped underground. Toad tells Fox about the dwindling Frog numbers due to the rats eating them and Fox agrees to get the foxes to stand guard around the pond. Whistler informs Plucky about the events happening in White Deer Park and how they need his help to fight the rats. When the gates to the new reserve open to let out a van Plucky takes his chance to escape and jumps into the back of the van. However it goes the wrong way, but it is forced to stop when sheep block its path. Plucky jumps out and races back to White Deer Park. Meanwhile Owl is devastated when Hollow tells her about the pretty young owl he intends to become his mate once mature. Owl refuses

Toad and Spike invent a game called "The Mole Game" They have to guess where Mossy the Mole will come up. Ranger ends up winning when Charmer asks what Toad and Spike are doing, which quite makes his day. Adder has vowed to kill as many rats as she can to avenge her mate's death. Owl is still imprisoned in her Jacket of building cement, a few other fellow flappers (A Robin, A Green Woodpecker, A Rook, and another female owl) decide to try and break the cement by shoving her off the branch, but the plan fails, she is off the branch and still in the cement (It made her feel very Slow and Heavy). Toad and Spike continue playing their game, but soon become surrounded by Bully and his rat army, Spike's cover is blown when he responds to Bully's Call of "Who am I" With a "Bully Bully Bully" complete with salute! Toad tries to escape, but ends up captured. Mossy has rushed to get help, only to find Dash. Dash goes and gets some White Deer to chase her, they stampede over the rats, squashing nearly every one. Spike feels awful for his behaviour, but is relieved when Toad is found alive at the pond, and Toad fully forgives him when Spike promises to fight like a Terrier the next time it happens. Spike was kicked out of the rat plague.
