A small nuclear device is stolen and is being used to threaten Gotham City, so Batman enlists the aid of a criminal named Brill to identify the blackmailer...but first, the Caped Crusaders must survive some death traps arranged by Brill and his men.
Lex Luthor designs Weapon-X, a device that can drain Superman's powers and use them to power a weapon powerful enough to destroy Superman. Bert Talbot is supposed to use the weapon to help spring Luthor from prison but instead decides to try to use the weapon to destroy Superman himself.
Sir Edwin continues to slander The Silent Knight, and Squire Brian (SK's secret identity) impulsively says the SK will meet any challenge. Just then a battleax and note thump down. The Hooded Terror will exact tribute from anyone crossing the bridge through the Forest Perilous. Brian dons the SK's garb and follows Slasher the hawk to the bridge. He's snared, but even upside down routs the twin Hooded Terrors with Slasher's help. Still, the SK must accept a challenge on the jousting field, and even felled, grabs a lance and wins the bout - and a rose from fair Lady Celia.
