Kan det här vara Utan varning ?
A father and son go hunting in the mountains. Before they can begin hunting, which the son does not want to do anyway, they are killed by flying jellyfish-like creatures, which penetrate their skin with needle-tipped tentacles.
Some time later, four teenagers, Tom, Greg, Beth and Sandy, hike in the same area, ignoring the warnings of local truck stop owner Joe Taylor (Jack Palance). A group of cub scouts is also in the area; their leader (Larry Storch) is also killed by the alien creatures, while his troop runs into an unidentified humanoid and flee.
