And so DC's first (but far from last) rendition of PLASTIC MAN ends with a bangless whimper, though at least Drake managed a few okay gags this time.
This time the hoary plot is "sidekick gets the main hero's powers." While Plas and Gordon participate in a parade, they're attacked by murderous doll-sized humans. Plas repels the attack but in the ruckus Gordon is injured. He needs a blood transfusion right away, so Plas donates his chemically-altered corpuscles, and Gordon gets stretch-talents.
Being a straight-arrow, the former sidekick presumably grows a Plastic Man costume out of his own skin and decides he'll show Plas how a proper superhero conducts himself. Naturally, he bungles all of his efforts, though at least this yields a peppy new version of the "Mabel, Mabel" song.
Meanwhile Master Mannequin, the mad genius behind the doll-men, unleashes his shrunken pawns upon a party thrown by Miss DeLute.
Plastic Man shows up late to the party. He's almost stymied by a doll-man who takes Micheline hostage, but Gordon's inadvertent entrance distracts the crook, and so Plas is able to overcome both the dolls and their master. The hero also gets the last words of the series, "So who needs neat?" There's more poetry than truth in this statement, for the Drake PLASTIC MAN is kind of a mess. But every once in a while, he worked a few good jokes into the chaos.
