A robbery and a betrayal begin this convoluted crime drama. Following a robbery, jewel thieves Dr. Sandegg and Klotz demand that the corrupt jeweler behind their latest heist give them a bigger cut of the take, but he cannot as he has already spent the loot. Instead, he gives them the key to his ex-wife's hotel room so they can steal her large diamond ring. Sandegg does the dirty work. Unfortunately another crook, Diehl, steals the ring from him. Diehl is involved with the ex-wife and after teaming up with Sandegg and Klotz, informs them that the ring they took was a fake. Diehl devises a complex plan to get the real stone. ~ Sandra Brennan, Rovi
