Rich young playboy Gregory Kirkland reads a newspaper story about a daring robbery, and bets his friends that he can steal a famous diamond tiara, The Sultana, from its designer and then secretly return it without being caught. Robert Sautrelle, who designed the tiara, visits Kirkland's home, and Gregory does indeed steal it. However, he gets cold feet before he returns it and convinces a woman he knows, Virginia Lowndes, to return it. Unfortunately, things don't work out exactly as Gregory had planned.—[email protected]

The midnight son of the House of Kirkland, inspired by the reading of a daring holdup by a band of masked bandits, makes a wager with his club mates that he can duplicate the stunt by holding up a man named Sauterelle and stealing from him The Sultana, a priceless jewel, and then return it to him without his knowing who took it. The foolhardy lark is accomplished, young Kirkland barely escaping detection, and then his nerve deserting him he asks Virginia Lowndes, a guest at the Kirklands, to help him out by returning it. She agrees to do it for him, but the jewel's presence has been discovered by the butler, a man with a doubtful past, who follows her auto and gets possession of it. From that time The Sultana changes hands in rapid sequence, once at the cost of a human life, but finally it finds its way back to its rightful owner, and is also the means of two hearts finding each other.—Moving Picture World synopsis
