Kai lives on a rural council estate in Somerset with his three older sisters, and his mother who is being led into an addiction by his troubled father. Kai adores three things: his dad, his friend Saffie and the school rabbit Flopsy - and is full of ambition to be the fastest runner in Middledown Primary. But Kai's natural optimism and energy collide with an adult world he doesn't understand. And when his life drifts towards an event that will change everything, will his love of nature and the wild rabbits in the woods provide him with the resilience he needs to overcome the odds?
