Hot jewels from London make their way to New York, where they are stolen by racketeer Ed Dexter, who hides them with the help of his vivacious girlfriend, Vivian Palmer. Federal agent Ross McBride goes undercover to infiltrate the gang and, suspecting Vivian can lead him to the jewels, comes to her aid when she is chased by a rival gang. The two flee to the Midwest with both gangs in pursuit, but Vivian is not as gullible as Ross thinks.
