The Dallas Cowboys Cheerleaders come on board as part of a charity fundraiser for an Acapulco orphanage. One of the cheerleaders enlists the help of her friends to dodge the advances of a persistent suitor, who has followed her onto the ship. A cheerleader's mother mistakenly fears that her daughter is trying to steal her boyfriend.

This complicates his romance with one of the cheerleaders. A divorcing couple plots to steal a valuable gem, which is hidden in a lamp that keeps getting passed between crew members. A famous dancer/actress who is helping with the charity event repeatedly declines Capt. Stubing's request that she take part in the performance. She is annoyed by the presence of her ex-fiancé, a notoriously tough theater critic.

A jealous Stacy comes to regret pushing Mark away. Wendy and Bill try to stop her mother from leaving after she misinterprets their purchase of wedding rings. Paul tries to keep his boss from learning about his girlfriend; and Lisa from learning about his ""family."" The Haymans have second thoughts about the diamond heist--and their break-up--after meeting the kids from the orphanage. Stella stings Elliot when she offers her harsh opinion about his play.
