Meanwhile, the police track and arrest Joe Rolfe, the innocent deliveryman of the real flower truck. They then drive the fake flower truck into an unmarked trailer, where Foster informs his crew that they will split the money at a later date, and gives each half of a playing card with which to identify themselves. Pretending to be flower deliverers, they rob the armored bank truck of over one million dollars. On the day of the robbery, the four men, who also are masked to protect their identities, wait until the flower delivery truck pulls away from the curb, and then pull up in an identical truck. Wearing a mask, Foster visits each separately and secures their services by threatening to turn them in to the police. Satisfied that each truck leaves at exactly the same time every day, he then assembles a trio of criminals to help him rob the bank of its deposit: Pete Harris, a gambling addict Tony Romano, a ladies' man and Boyd Kane, a cold-blooded killer.
For over a week, retired Kansas City police captain Tim Foster watches the Southwest Bank and the flower shop next door to ascertain the timing of each business's delivery trucks.
