Plot: An alien couple known as Beldar and Prymatt with cone-shaped heads from the planet called Remulak is mistakenly ditched on earth, during a scouting mission for planet conquest. While here, they dodge the INS, have a child and discover that life on Earth is quite good. But unfortunately they are being chased by the government who knows something is not quite right with the Conehead family. After they are rescued and taken back to their planet, Beldar vows to return to earth and conquer it.
Alternative Plot: Cone-headed extraterrestrials Beldar (Dan Aykroyd) and Prymaat (Jane Curtin) find themselves in New Jersey after a recon mission for their home planet of Remulak goes awry. Stranded, they are forced to live as typical suburban humans. Beldar gets a job, and daughter Connie (Michelle Burke) grows up to be a typical, if oddly shaped, teenager. When INS agents start investigating the family and Beldar receives sinister orders from Remulak, the Coneheads must decide where their allegiance lies.
