Alien Intruder

Four convicts get a chance to win their freedom by volunteering for what seems to be a routine salvage mission in space. Out of nowhere appears a mysterious and beautiful woman-which should be a welcomed event for four men confined in space! But soon, the captain begins to lose his grip on sanity. Crew members start dying. The Navigator-the only one who finally sees what's happening- realizes there's an alien on board with a deadly mission of it's own. Is it too late?
