Three sisters, Veronica, Victoria and Elizabeth, receive letters from their late father's lawyer informing them of their father's wish that they spend three nights in his house on an isolated island before his will can be read. They and their husbands William, Richard and Donald are met there by the two maids, Martha and Ruth, and a hunchback named Colin whom the audience has already seen murdering two people at the beginning of the film. While helping with the luggage Colin becomes angry and catches and eats a live rabbit. The remains of the rabbit are later found in Veronica and William's bed, along with a note reading "Blessed are the meek for they shall inherit".
