Synopsis:
Five Justice League members are teleported to the planet Marithania by its rulers, the Impossibles, to have their super-powers taken away on the grounds that, whereas their fellow members have earned theirs, these members came by their abilities by mere chance. (Superman, Aquaman, and the Martian Manhunter gained their powers by accident of birth, Flash received his super-speed through an accident, and Wonder Woman's abilities were a gift of the goddess Aphrodite.)

When the Impossibles' enemies, the Contras, attack, the powerless heroes are forced into battle, and actually benefit from their loss, because their various weaknesses have also disappeared. In a second encounter with the Contras, the JLA members regain their powers through a series of accidents, and this time the Impossibles allow them to retain their abilities.
