A commercial crew aboard the deep space towing vessel, Nostromo is on its way home when they pick an SOS warning from a distant planet. What they don't know is that the SOS warning is not like any other ordinary warning call. Picking up the signal, the crew realize that they are not alone on the spaceship when a alien stowaway is on the cargo ship.
