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.
