In a tranquil and ordinary world, peace is disrupted when a group of extraterrestrials, with quite a peculiar appearance and several flying saucers, decides to pay a not-so-friendly visit to Earth. Dr. Russell Marvin, a dedicated scientist, finds himself at the epicenter of this galactic invasion. Along with his wife, things turn personal when the aliens, fearing humanity and its destructive potential, begin to ravage major cities, reducing monuments to rubble and sowing panic among the population.
Determined to save his home, Marvin must not only face the devastating attacks of these strange creatures from another world but also decipher the enigmatic purpose behind their visit. As the government remains skeptical and reluctant to believe in the threat, Russell's ingenuity and his ability to create anti-aircraft weaponry become humanity's last hope.
With special effects that, although they may seem a bit dated today, dazzle with their retro charm, the story unfolds in an atmosphere charged with tension and a touch of unintentional comedy. In this fierce battle for survival, Russell and his team must find a way to communicate with the extraterrestrials before Earth falls under the yoke of an intergalactic empire. Will humanity manage to unite and confront these invaders, or will it be yet another chapter in the story of Extinction?
