House of the Last Man On Earth

Richard Johnson, a college student, just spent his last dime on food, lost his wealthy girlfriend, and had his bike stolen. To add to his misery, he returns to his apartment where he runs into his strange neighbor. Convinced this bizarre man is more than he seems, Richard and his land lady's bull dog, Khan, sneak into his apartment where they find a timegate to the future. Along with his set theory teacher and her brother, they embark upon a soaring and treacherous journey through space and time to discover a terrible truth-mankind is being slowly and systematically exterminated.
