Blueprint for Robbery(1961)

A gang of career criminals plots the robbery of an armored car company's headquarters. Although the robbery itself goes off as planned, it's not long before the gang members are fighting among themselves over everybody's share of the loot and trying to avoid capture by the police, who are pouring all their resources into capturing the robbers. Based on a real-life 1950 Brinks Armored Car Co. robbery in Boston.
