Earth vs. the Flying Saucers

Scientist Dr. Russell Marvin and his young wife Carol are driving to work when a flying saucer appears above their car. Dr. Marvin accidentally records the sound made by a UFO on a tape recorder, but since he has no other evidence, he reluctantly notifies his superiors about the event. He is told that he probably saw one of the ten research satellites launched by the American space program Project Skyhook, in which Marvin himself works.

General Hanley, Carol's father, informs Marvin that many of the Project Skyhook satellites have fallen to Earth after launch. Marvin admits that he has lost contact with them and suspects a foreign sabotage. Next, Marvin witnesses the fall of the eleventh satellite almost immediately after launch.

The next day, a flying saucer lands at the Skyhook training ground, a group of aliens in metal suits comes out of it. The polygon guards open fire and kill one of the aliens who has gone beyond the force field of the saucer. In response, the aliens destroy everything at the facility and kill everyone except the Marvin couple, who accidentally find themselves locked in a bunker. Aliens kidnap General Hanley. Sitting in a locked bunker, Russell discovers and decrypts a message on his tape recorder: the aliens wanted to meet Dr. Marvin and landed at the landfill for this purpose. Unfortunately, it's too late.

Marvin communicates with the aliens on the radio at the frequency indicated by them and goes to meet them. He is joined by Carol, Major Huglin and a police patrol officer. They voluntarily board a flying saucer, where they discover a general whose memory has been erased as a result of transferring information to the ship's computer. The aliens explain that they are the last of their kind, because their star went out, and they fled from the destroyed solar system to find a planet for colonization. They shot down all the launched satellites, fearing that they could be used as a weapon against the aliens. They offer the earthlings to surrender so that the colonization will take place without resistance and sacrifice. To prove their strength, the aliens destroy a US Navy destroyer and give Dr. Marvin the coordinates of the place of its flooding. The patrolman shoots a pistol, and the aliens subject him to the procedure of transferring information and erasing memory. Major Huglin and the Marvins are released to transmit to Earthlings the message that the aliens want to meet with world leaders in 56 days to discuss the occupation of Earth.

Dr. Marvin's research shows that the protective suits of aliens are made of solidified electricity. Marvin develops a weapon, which he later successfully tests on one of the flying saucers. During the flight, the aliens throw General Hanley and a patrol officer out of a flying saucer (both fall from a great height and crash). After that, groups of alien ships attack Washington, Paris, London and Moscow, but meet desperate resistance and are destroyed by Dr. Marvin's weapons. It is also discovered that aliens can easily be killed by simple firearms when they are outside the force fields of their plates.

The threat is eliminated, Dr. Marvin and Carol calmly celebrate the victory, returning to their favorite beach and resuming their honeymoon.
