The body of a teenage girl is found on the beach in the days leading up to Christmas, 1980. It's an event that makes a huge impact on all those who live along Rocking Horse Road, which runs through the Spit, a long 'finger of bone-dry sand' between the ocean and the estuary. It's an event that for one hot summer brings together a group of fifteen-year-old boys and then keeps them linked for the rest of their lives.
