Peter Smith is waiting for a bus one day when a car pulls up and the occupants ask him if he wants a lift. Persuaded to take them up on the offer by the gun they are pointing at him, he is driven to a bizarre old man calling himself The Major who offers him a job. All Peter has to do is take a briefcase to an address 100 miles away.
However, the briefcase is soon stolen from under his nose, and he finds himself embroiled in a crazy world of rival drug smugglers and secret agents - and all of them seem to want Peter dead.
