A nameless, ruthless man Preston Foster who identifies himself as Mr. Big is timing to the minute the arrival of two trucks. One is an armored car routinely picking up bags containing lots of money from a bank. The other truck delivers to a flower shop next door. The mans timing shows that, for a very few minutes, the schedule of both trucks coincidentally parks them next to each other. He is casing the armored car. He needs a gang to help him rob it.

Big and his gang subdue the armored car guards in four minutes, grab bags containing 1.2 million and flee, knowing that his distinctive getaway truck will be mistaken for Rolfes.

Ive got everything covered, but in case something does go wrong, and I cant make the payoff myself, the cards will identify you to whoever I send with the money. When the gang members object, Big tells them, intensely, You cant even rat on each other because youve never seen each other without those masks. Ive made you copp
