When the unthinkable happens, six-year-old Zach is at school. Huddled in a cloakroom with his classmates and teacher, he is too young to understand that life will never be the same again.

Afterwards, the once close-knit community is left reeling. Zach s dad retreats. His mum sets out to seek revenge. Zach, scared, lost and confused, disappears into his super-secret hideout to try to make sense of things. Nothing feels right – until he listens to his heart . . .

But can he remind the grown-ups how to love again?
