In a typical American suburb of the 1970s, an alien named Prymaat and her husband Beldon, both with distinctive cone-shaped heads, arrive on Earth on a mission of exploration. However, what begins as a simple space excursion turns into a hilarious comedy of errors when they decide to settle in the city despite their complicated accent, strange lifestyle, and intergalactic cuisine.
The young couple tries to adapt to human life, but it proves to be challenging, especially when faced with the hilarious difficulties of raising their daughter, Michelle, in a world unprepared for their quirks. As their attempts to fit in become increasingly absurd, attention from the authorities focuses on them, leading to a series of misunderstandings and ridiculous situations. From trying to understand local customs to dealing with the FBI on their tail, the cone-headed family embarks on a whirlwind of laughter and lessons about acceptance and family love.
When their true identity is threatened, they must join forces to protect their home and way of life, confronting both the authorities and their own fears. With a stellar cast and a witty script, this comedy becomes a charming portrayal of how being different can be both a challenge and a blessing.
