Two pilots are at the controls of the SS Madame de Pompadour. Suddenly, an ion storm hits the ship, causing chaos as lights start flashing and things start exploding, with the two pilots desperately trying to regain control. One of them shouts, "Mayday!" as the scene blacks out. Later, the same cockpit is now bathed in a red light and both of the pilots are on the floor, one presumably dead. An eerie tick-tock noise is heard. A shadow falls over the surviving pilot, who is at first relieved to see help. Her relief soon turns to terror, as she suddenly becomes scared of whatever is looming over her, and she screams. A clock face cracks — part of a clock situated on top of a fireplace...
