A casino manager (played by Tony Curtis) and his club singer, Chris Lockwood (played by Suzanne Pleshette), find their hands full when they agree to take in a troublesome young girl named Penny Piper (played by Claire Wilcox), left behind in the casino by her gambling father. The little girl hinders the manager's plans to keep his gaming licence. Penny thinks that Steve needs to get married and settle down, so she starts trying to match make, trying to set him up with Chris.
