The wealthy Mr. Van Decar and his wife Sondra discuss a party they're getting ready for. They complain about the gossiping Patricia Markman. Sondra puts on her jewel necklace and finds that it's been booby-trapped to puncture her throat. Later, Commissioner Gordon discusses this case with Detective David Esteves. They know it was the recently released Magpie, but they have no idea what her pattern is. Batman arrives at GCPD Headquarters and explains that he deduced Magpie's game. Her victims were Sondra Van Decar wearing the "Eagle's Heart" ruby, Mrs. Andreason wearing a "Robin's Egg" sapphire, and Mrs. Lewis wearing a "Turtledove" emerald. Magpie is collecting birds and killing her victims. Batman suggests that they set a trap using the "Wayne Collection" of jewels because Bruce Wayne owes him a favor. Jim Gordon sets up a sting operation at Wayne Manor. Detective Roberta Valle poses as Bruce Wayne's date, wearing the Falcon's Eye Diamond. They are interrupted by the pundit G. Gordon Godfrey, who starts an argument about Gordon's dependence on Batman. Gordon and Wayne both defend Batman as a necessity, but Godfrey insists that no superhero can be trusted. Godfrey suggests that Batman inspires his villains, and Bruce Wayne replies that "evil creates its opposition." Godfrey spills a drink on Valle. This is cleaned up by an attendant, who is revealed to be Magpie. Magpie replaces Valle's necklace with a lethal one and escapes. This releases nerve gas, and Bruce Wayne quickly switches to become Batman. He is unable to save Roberta. The crowd sees Batman helping, but Godfrey convinces some that Batman was attacking them. Batman returns to the Batcave with Robin to search for Magpie in the Batmobile. They investigate Magpie's previous nest, the Gotham City Museum of Antiquities. There is a truck outside labeled "Grouse Catering", which explains her infiltration of Wayne Manor. Inside, Magpie admires her collection with her three henchmen. Batman and Robin easily take down the thugs, but Magpie escapes with the Falcon's Eye. Magpie seals her lair and activates a laser death trap with all five men inside. Batman can deactivate the trap by using one of her gems as a reflective prism. Batman runs outside and confronts Magpie, who dropped the jewel and is struggling to grab it. Magpie threatens to shoot him with an explosive dart, but Batman reveals this will also harm one of her jewels. Magpie has an emotional breakdown, and Batman walks her outside. They walk into the sunrise and Magpie says "You are a horrible man." Batman replies "I am what I have to be." -LCG
