Sky 1 intercepts a UFO over the north Atlantic and shoots it down over the sea. The Alien survives, and is captured in the net of a new hi-tech fishing ship, where he kills the crew. Ordering the skipper to make a bomb, a signal is sent out to lure Skydiver in to a trap. Skydiver is ensnared by the metal fishing net and the Alien throws an explosive on-board. But the Alien has reckoned without the skipper, who harpoons the Alien, allowing Carlin to get the bomb and throw it into the sea before it explodes.
