Overview
Roger has invited his old friend Philip and his wife for a cruise on his luxury yacht together with Denys and his wife Valerie in order to see whether Denys, his employee, proves suitable for an important job abroad. All seems set for a restful holiday. Complications start with the very first arrival, Roger's estranged wife Lisa. Then the philandering Philip turns up with super sexy Mercy instead of his wife. Soon every conceivable permutation and combination of twice three has been achieved, with the clumsy Denys losing his contact lenses and stumbling around doing damage everywhere. Even Roger's unseen secretary Betty Samuelson is drawn into the plot before the final hilarious and unexpected climax.
