Without Warning (1980) 720p BrRip x264 - YIFY

A hunter and his son travel in a RV to hunt in the woods of a park. Out of the blue, they are attacked by flying amoebae-like and die. When a scoutmaster stops at the location, he releases the boy scouts to play at the creek but is murdered by a flying amoeba-like and the boys flee from the spot. Meanwhile, the teenager Tom invites the teenage girls Beth and Sandy to go to the lake in the park with his friend Greg. He stops his van at the gas station to fuel up and the owner, Joe Taylor, advises them to not go to the park since is dangerous. However, they go, and Tom and Beth vanish. Greg and Sandy look for them and find their bodies in a shack with the bodies of the hunter, his son and the scoutmaster. They run to the van and drive to a bar, where the clients do not believe in Greg. Only the lunatic veteran of the Vietnam war, Fred 'Sarge' Dobbs, gives credit to his words. Taylor arrives at the bar, and the mad Sarge believes that Greg and Sandy are alien. Taylor asks them to show where the shack is, since he believes the alien is a hunter and the corpses are his trophies. Now the alien hunter will become Taylor's pray.
