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. A man, who has been lying to his boss about having a family, hires a group of actors to pose as his mother, wife and son for the company's "family cruise." 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.
