S1·E14 Countdown

A mysterious person who calls himself "Viking" has just bombed the cruise ship Victoria, underway in the North Pacific Ocean. He demands six million dollars or another bomb will go off within hours. So MacGyver gets called in, along with his old Vietnam bomb-defusal partner, Charlie Robinson, to disarm it. But when they get there, they find out there's more than one bomb on the ship. Complications arise when MacGyver's partner sets off one of the bombs, and the bomber decides that DXS operated in bad faith and refuses to hand over the bomb-disarming instructions after he gets the extortion money.
