Note: The location of the events in this film are unknown.
Full titles read: "ONE MILLION VOLTS - Bigger and better sparks - higher and longer leaps - is the outcome of these lightning-like electrical tests, at enormous voltages."
Several shots of large electrical equipment. The lights suddenly go out and the room is suddenly lit up by the electrical flashes and sparks (it looks like forked lightening), and the crackle of electricity.
