Graeme Willy and Clive Gollings are British comic book enthusiasts and best friends who travel to the United States to attend the annual San Diego Comic-Con. Later, taking a road trip through the Southwestern U.S. to visit UFO sites on a remote desert highway at night, they brush with rednecks at a diner, They watch a car driving erratically and then crashing. They then stop, offering assistance to the driver, an alien named Paul (Paranoid Alien Ultra Life-Force), who Graeme agrees to give a ride to, despite Clive fainting and wetting his pants upon seeing him.
