Synopsis

After performing in a concert, Donny and Marie Osmond head for the airport to catch a flight to Hawaii. At the airport, they wait for a telephone booth occupied by Charlie, who unbeknownst to them, is a member of a theft ring. Charlie is making a phone call to his boss, Wong, to inform Wong that he has retrieved a necklace Wong wants and to warn him that a man named Webster, who works for a Professor Kruse, also wants the necklace. As Donny and Marie wait for Charlie to finish his phone call, an attractive blond woman named Tricia approaches them. Donny flirts with her, but she has no interest in him. Meanwhile, Charlie sees Webster approaching and gives the necklace to Marie, telling her it is a gift to her from his church, and Tricia sees him do it. A few moments later, Webster corners Charlie and demands to know the whereabouts of the necklace, and Charlie denies having any knowledge of it.

Donny sees Tricia in the hotel lounge and asks Marie to leave them alone, so Marie heads back to their hotel suite. Donny approaches Tricia and asks her out, but to his disappointment she suggests that Marie come along. Meanwhile, Marie returns to the suite to find Mickey ransacking it as he looks for the necklace. While Donny is walking Tricia back to her room, he hears Marie scream and rushes to their suite. He finds Marie fighting Mickey off and jumps in to protect her. Mickey flees and Donny pursues him out of the hotel, but loses him in a crowd of fans.

To communicate with him, Kruse shows him a picture of Donny and Marie and tells him to wiggle his toes to answer yes-or-no questions about the picture. Meanwhile, Ito turns on the television, on which he and Kruse see Donny and Marie performing on a local television show and Kruse notices that Marie is wearing the necklace. At the television studio, Sid introduces Donny and Marie to Al, their new security guard. On stage, Marie notices Wong staring at her in the audience and becomes flustered, forgetting the lyrics to songs.
