Johnny (Gregory Moffett), an annoying all-American boy, is sleeping off his picnic with his parents. He wakes up and reaches a cave, suddenly the world is torn upside down, dinosaurs fight in a valley, most of the human race is wiped out and... an alien gorilla in a space helmet is looking to complete the job!
What is going on? Why have we gone from a picnic to a post-apocalypse scene were just a handful of humans are left alive in just the blink of an eye? Apparently the survivors are protected from the evil cosmic ray weapon of Ro-Man (George Barrows/John Brown) by a serum developed by The Professor (John Mylong). Ro-Man, despite his space simian nature, puts his plans to complete the wipe out of humanity when he takes a fancy to Johnny's older sister Alice (Claudia Barrett)...
This is very low budget fare, for some reason Ro-Man has a bubble making machine. Nothing really makes sense, well when we do get the twist it kind of explain a lot of the nonsense we have just seen. Very strange stuff indeed.
