Synopsis:
Some Martian Mandrills, ape-like Martian animals, attack the city and rob banks. J’onn can’t understand where they came from until he locates a crashed rocket outside of town. Missing from the rocket is a control device which can control the Mandrills. J’onn tracks them to a gang of crooks. The police use fire against the Mandrills while J’onn captures the gang. Then the Mandrills are rocketed back to Mars.
