It’s winter, 1940. The Clarkes are an average family, going to their father's war posting in Italy. However, when their pilot deliberately crashes their private plane, things take a turn for the worse. Troy, the dad, becomes stranded on an island with his son, Michael. Sophie, the mum, also becomes stranded on a separate island with her two daughters, Mae and Lilly. Both groups, completely stranded. Will the Clarkes get their revenge? Will they ever escape? How will the family deal with being separated? But the biggest question of all, will they make it home...alive?
