Security van seen in action as four tough men collect a payroll from a bank.
M/Ss of Sir Percy Sillitoe, "one-time head of MI5 and now in charge of Britain's foremost security service". He is showing four uniformed security guards the route that their security van will take with the help of a map of London on the wall and some model cars on a model road on the table. The "four tough men" are seen getting into the armoured van and driving off.
It stops to let one of the men out to check out the pick up area; he walks up and down before a branch of the Westminster Bank, looks at his watch and watches out for the van and any suspicious happenings. A man at headquarters speaks with a man in the van via an intercom (the man in the van seems quite bored), telling him it is safe to proceed.
M/S of the van pulling up outside the bank; two of the men go inside with a large bag, one stays in the van and the other keeps watch on the pavement outside. The two guards are seen inside the bank as a bank man opens a vault and puts a sealed bag (presumably containing the payroll) inside the guard's bag; one of the guards attaches a chain to the bag that is fixed to his person (somewhere!).
M/S outside the bank as the lookout guard gives them the all-clear signal to come out.; we can now see a sign on the bank reading 'No.s 1 & 2 Finsbury Square'. Looking left and right they all walk over to the van, get in and drive off.
Note: The security firm featured is 'Security Express'.
