Two cut-rate private detectives are broke, hungry and down to their last nickel. They decide to hock their banjo in order to get some money for food, and while one partner is negotiating the deal, the other one falls asleep and dreams that a wealthy society matron has hired them to investigate a string of suitors.
Tommy McCoy and "Dude" Markey are both in love with Harlem singer/dancer Nita. Markey robs a jewelry store and turns the loot over to gang-boss Murray Howard. Later, Markey robs the safe, steals the jewelry, and, in order to get rid of his rival for Nita, frames the robbery on McCoy. The latter's big-brother thinks otherwise and, with Nita's help, sets out to prove it.
