It's hard to imagine the vivaciously stylish Constance Talmadge as a boarding-house drudge, but that's the part she plays here. An old couple resides at the house with a mysterious box, which they watch over constantly. Harry Brent, an equally mysterious young man (Kenneth Harlan), moves in and convinces Betsy that there are items in the box that belong to him, and she obligingly steals it. Oscar, a grocery clerk and aspiring detective (Clyde Hopkins), believes that Harry is a crook. There are real crooks afoot, but they have nothing to do with Harry. They kidnap Betsy and the box (which she emptied into her trunk before their arrival), kill the old husband (Joseph Singleton) and knock Oscar --who is in the couple's room -- unconscious. Harry gives chase while Oscar comes to and calls on some real detectives. The police capture the crooks, and Betsy reveals the contents of the box -- the Brent family jewels and a will in Harry's favor. ~ Janiss Garza, Rovi
