Twin brothers separated at birth who through a different environment, turn out as opposite from each other as can be imagined. Jules Benedict (Schwarzenegger) has been raised in an ideal environment where he has developed his perfect specimen physique and high-minded intellect. His "twin" Vincent Benedict (DeVito) is a small-time hustler willing to try any imaginable scam to make a buck. When the two are reunited, the clash between personalities and morals has the two deeply involved in a life-threatening caper involving master criminals that want to steal powerful technology. Marnie Mason (Kelly Preston) and Linda Mason (Chloe Webb)are sisters who provide romantic relief, becoming involved with the Benedict "twins."
