tiny space creature, bent on destruction, is captured by the scientist Mordecai Spazman. His rival, professor Harvey Kry, convinces the media that Spazman's claims are bogus. The vengeful Spazman boxes up the invader's miniature spacecraft as a wedding gift, presenting it to Kry's son. The alien imprisons Harvey Jr. inside the ship, to force Dr. Kry to help him complete his mission.
