在这部外星奇缘喜剧/音乐/爱情片中,一艘太空船撞进了吉娜·戴维斯的后花园，她与女友茱莉·布朗将外星人的手剃去后，发现他们都是靓仔，于是带他们扮靓买衫，过着美国人式的生活。
Three furry (and funny) aliens travel around the universe in a spaceship and receive a broadcast showing human females. They are fascinated by these shapely creatures and discover that the broadcast came from Southern California on Earth. Meanwhile, Valley girl Valerie Gail feels her cold fiancé Dr. Ted Gallagher is slipping away and decides to seduce him. Instead, she catches him cheating on her with a nurse, throws him out, smashes his things and refuses to see him again. The aliens' spaceship crash lands in Valerie's swimming pool - putting a decided damper on her future wedding plans in Las Vegas. She brings them into her home; and the aliens prove to be quick learners and absorb American popular culture and language through television.
