Aliens visit Earth, their flying saucers flying over Tokyo. Unfortunately the aliens find, as they look like giant walking starfish with a single eye, cannot approach humans without sparking panic. The aliens indeed do want to desperately contact humanity as a giant meteor is heading to the Earth...
One of the starfish aliens therefore decides to disguise herself as a popular Japanese singer (Toyomi Karita)! Mankind is finally warned about the meteor and scientist Dr Kamura (Bontaro Miake) scrambles to develop a weapon to deflect it before it's too late. Things are complicated by enemy agents who want to use the weapon for themselves...
The film has a fair amount of Japanese whimsy though is a bit slow at times. The story is interesting if a bit vague at times, the aliens being the good guys a nice twist for a 1950s science-fiction film.
