Five sisters embark on a journey to a new home, to Brighton, where Mary's (the eldest) fiancee lives. Having lost both their parents and being left practically destitute, the girls have no money to secure passage on a cruise ship. Fortunately, an old school friend of their father's, Charlie, owns a small ship and offers the sisters free passage on his ship, in exchange for light cooking and housekeeping duties. The girls gloomily embark on the small ship for a 3-month voyage along with Charlie, 16 sailors, and an invalid, changing their lives forever.
