A small group of extraterrestrials from Mars, who seem more like a cosmic joke than an intergalactic threat, is tasked with invading Earth. However, as often happens in these cases, the mission turns into a disaster when their spaceship gets lost and ends up landing in a quiet American town on Halloween night. Instead of being welcomed as heroes, these clumsy aliens find themselves amidst a celebration where children are enjoying tricks and treats.
Confused and excited, the Martians decide to take the opportunity to blend in with the humans, but their lack of social skills and their peculiar appearance lead to hilarious situations and misunderstandings. Meanwhile, a group of teenagers and an enthusiastic elderly man obsessed with horror movies become the unexpected heroes of the story, trying to protect their home from the invasion, unaware that the extraterrestrials are more comedic than threatening.
As the night progresses, the aliens find themselves caught between the celebration and their attempts to fulfill their mission, triggering encounters filled with laughter, a couple of scares, and a good dose of 90s nostalgia. The film captures not only the essence of sci-fi movies from the era but also the magic of Halloween, offering a fun glimpse into how friendship can arise even among the most unexpected beings in the universe. A classic you won't want to miss!
