The Amant cruise liner has a destination for Brazil, an intriguing new landscape for Donna. Donna Capers - a young London girl coming from a sheltered, upper-class life - decides to finally leave Europe with her new husband. With her first act of independence without the assistance of her over-bearing father, she - taking her best friend and personal maid, Nellie, with her - cruises to America to commemorate her new life. Little does she know the characters she will meet or the fate that lies ahead of her. The stage is set for murder, but who committed the crime, and what was their motive. Is Donna safe from the unrest that floods the ship, or is she destined to fall alone?
