The men in black are amoung us. Sinister assassins intent on silencing human witnesses of all UFO sightings...permanently! But the true mission of these savage strangers led by the evil 'Marcabian' with unusually pale skin and glowing eyes goes further than any simple cover-up of the Roswell aliens or flying saucer landings. They are an undercover advance guard from an extra-terrestrial race. Ruthless warriors from a distant planet, who have hoodwinked our politicians with the promise of incredible technological advances in exchange for their secret co-operation. But far from being for the benefit of Mankind, the time space portal the strangers are covertly building is really the signal for Earths armageddon - a wide open gateway for alien invasion. Only a sceptical government agent (Jack Scalia), a mysterious intergalactic peace-keeper (Dennis Christopher) and a stunningly attractive female journalist (Lucinda Weist) stands between the extra-terrestrial army and the total annihalation of the human race. The Silencers.....They're here and they're hungry for conquest.
