Warning from Space

A small ship travels to a rotating space station. Aboard the station, a group of starfish-like beings discuss how to warn humans of an impending disaster, deciding on contacting Japanese scientist Dr. Kumara. Meanwhile, flying saucers are spotted over the skies of Tokyo, baffling scientists. A journalist tries to get a statement from Dr. Kumara about the sightings, but Kumara replies that there is not enough evidence to formulate a hypothesis. At an observatory, Professor Isobe spots an unidentified flying object in his telescope apparently releasing smaller objects.
