A shape-shifting reptilian alien, who's escaping global cooling, lands on the couch of Jamie, an unemployed bloke in suburban Rockingham, south of Perth. The alien smokes marijuana, follows the Fremantle Dockers, and speaks with a broad Aussie accent. He, and the rest of his race, have been watching our TV through a wormhole in space. They're planning to invade us, and save our planet, the same way they killed theirs.
