Eva Rivers, in love with her employer, John Rogers, lives with two friends, Eileen and Pauline. Rogers, secretly a member of the U. S. Secret Service, is trailing Anthony Roche, owner of the Golden Calf Restaurant, whom he believes to be engaged in illegal activities. Eileen, who has become Roche's secretary, meets Rogers at the Golden Calf and casts suspicion on Eva's character. Eileen, Pauline, and Eva, accompanied by some of Roche's henchmen, visit Claire Mathers at her beach cottage. Discovering that Claire is a government agent, the men gag and bind her and kidnap the three girls, flying them to a coastal cafe. Claire escapes to notify the police, and Rogers, posing as Roche's partner, rescues the girls after Benson, owner of the cafe, accidentally shoots Roche.
