When their boat sinks while crossing the Timor Sea during World War II, a troop of young Australian soldiers must find a way to survive the harsh seas on a quickly shrinking raft. Hundreds of miles from anywhere, they must confront interpersonal conflicts, enemy attacks, and the advances of one very large, very hungry great white shark.

In a remote monastery in 1940s Australia, a mission for Aboriginal children is run by a renegade nun, Sister Eileen. A new charge is delivered in the dead of night – a boy who appears to have special powers. When the monastery takes possession of a precious relic, a large carving of Christ on the cross, the new boy encounters Jesus for the first time and is transfixed. However, the boy’s Indigenous spiritual life does not gel with the mission’s Christianity and his mysterious power becomes a threat. Sister Eileen is faced with a choice between the traditions of her faith and the truth embodied in the boy, in this story of spiritual struggle and the cost of survival.
