Four astronauts returning from mankind's first mission to Mars enter a time warp and crash on a 26th Century Earth devastated by atomic war. Our heroes meet with hideous mutant cavemen, giant spiders, love-struck beauties in short dresses, and jealous old geezers in sparkly skullcaps as they struggle to save humanity and build a new world. - IMDb
