Poachers enter the Park and kill some of the Deer. The Farthing Wood animals do what they can to help and set up a watch to act as an early warning system. Fox hatches a plan to rid the Park of the hunters but Scarface plots to turn his plan against him.

A harsh winter arrives and the Farthing animals are finding food scarce, especially because their recent arrival left them unable to stock food. Whistler and Speedy spare some of their fish for the meat-eaters, but the animals soon become sick of the same diet. While out hunting Fox and Vixen meet Scarface and his mate Lady Blue. Vixen tries to start a conversation with them but Scarface warns her to stay on her own land. Meanwhile Badger slips in the heavy snow while out walking and is injured. The Park Warden finds him and takes him back to his home to treat him. The other animals worry for their missing friend. Badger manages to persuade the Warden's cat to inform the others that he is safe. While the cat is telling Mole about Badger being with her at his cottage, Kestrel spots them and thinks Mole is in danger. She dives on the cat, injuring her and causing her to fall to the ground in pain.

With food scarce the animals are hungry and the meat eaters of the group are having difficulty hunting because they fear accidentally hunting one of their friends. While the smaller animals blame Fox for the recent death of Mrs Vole, Badger is released from the Warden's cottage.

Its spring and Vixen finally gives birth to her cubs. The animals all gather to congratulate the new parents and to help decide on names for the four cubs. The poachers still plague all the animals in the park but when the warden returns they believe their troubles to be over. However the poachers continue to hunt in the park while the warden remains ignorant to their nightly activities. Fox sets into motion a plan to get rid of the poachers by bringing them to the attention of the warden. Wandering round in the open and calling out they finally spot him and give chase - straight to the warden's cottage. Hearing gunshots the warden runs out and catches the poachers in the act, putting a stop to their hunting for good.
