Johnny's greatest weakness is for money: he always wants more and he's willing to do anything to get it. So when a mobster named Blackie suggest that they pull off a diamond heist together, Johnny agrees. Things get more complicated, however, when Johnny comes across his other weakness: women. Blackie's girlfriend is gorgeous and despite the danger, Johnny just can't resist. The price of letting things go south with Blackie however, might be greater than the loss of just one job.
