Sam Gavin decides to relocate his family from Houston, Texas to a sheep station in Australia to protect his eleven children from the "destructive influences" of modern American society. Because of business obligations, he fails to join them and, more or less, abandons his wife, Liz, to the hardships of her new surroundings. Mother and children are determined to make a go of it.

When failed novelist Amos agrees to mind his friend's research station on a remote island for just one day, he expects solitude and a chance to break his writer's block. But when his friend fails to return, Amos discovers he has been deliberately trapped in a bizarre time loop. In a desperate attempt to escape "yesterday", Amos coaxes his ex-wife onto the island, but instead strands them both there. To ensure their own freedom, the two must scheme to invite their most dislikeable friends to the island, with unforeseen and messy consequences. A quirky dark comedy about second chances, petty revenge, and the ultimate importance of forgiveness.
