Charlie and Dan have been best friends and business partners for thirty years; their Manhattan public relations firm is on the verge of a huge business deal with a Japanese company. With two weeks to sew up the contract, Dan gets a surprise: a woman he married on a drunken impulse nearly nine years before (annulled the next day) shows up to tell him he's the father of her twins.

Lem is just an average teenager working on getting the girl and furthering his career at the local planetarium - except that he's an alien. At least to U.S. astronaut Captain Charles T. Baker who lands on Lem's planet hoping for a quick flag plant and a hasty return to earth and his millions of screaming fans. But on this alien planet the media has tagged spacemen as brain-eating, zombie-creating monsters, causing Baker to run for his life and into Lem's house.
