 Posing as truck drivers, two men steal a $100,000 computer from Ferris Electronics and demand $100,000 in ransom for its safe return. The computer is large and unassembled, so Dan Mathews deduces that it must be hidden in a large building in a remote location. He arranges to have Richard Ferris get the ransom money from the bank, but an officer who resembles Mr. Ferris is assigned to take it to the prearranged rendezvous. The thieves panic when they realize that they are under inescapable surveillance by the Highway Patrol helicopter. One gives himself up and the other makes a frantic (and inevitably futile) attempt to get away in the rough terrain.
