Xtro 3: Watch the Skies Blu-Ray

A group of military personnel have been assembled to, they believe, locate and disarm old active explosives which have been left unattended at a former army testing site on a remote island. But when they arrive at the deserted island, they soon discover that something doesn't seem quite right about their mission. Soon enough, they uncover a strange concrete block which, after accidentally blowing up, unleashes an indestructible, bloodthirsty alien being which will stop at nothing to kill them. As the survivors band together in order to stay alive and try and find a way to outwit the diabolical creature, they realize that their entire mission might have been a trap and that the military is using them as pawns in their own vicious plan...

The third and most violent entry in the XTRO trilogy, Harry Bromley Davenport's XTRO 3: WATCH THE SKIES moves the setting to Southern California while amping up both the action and the gore, through a series of nasty and inventive death scenes.
