A Man, a Woman and a Bank (1979)

The two least likely bank robbers in the known universe plan and execute... kind of... the ultimate heist.

Two novice thieves are plotting to rob a bank in Vancouver. A photographer snaps a shot of one thief as he is carrying the bank building's blueprints. The would-be thief then begins a relationship with the photographer and attempts to retrieve the photos. Meanwhile, the thieves' plot consists of this: one man will enter the bank building after dark, while the other man sits in a van and uses a computer to unlock the building's doors. The final step involves transporting the cash to a freight ship waiting on the docks, for transportation to a money launderer in Macau.
