Batman Returns

In the prologue, socialites Tucker and Esther Cobblepot give birth to a deformed baby boy, Oswald. Disgusted by his appearance and wild demeanor, they confine the baby to a cage and ultimately throw him into the sewer, where he is discovered by a family of penguins at Gotham Zoo.

Thirty-three years later, millionaire Max Shreck proposes to build a power plant to supply Gotham City with energy, though he is opposed by the city mayor. During Shreck's speech, Gotham is attacked by a disgraced former circus troupe, the Red Triangle Gang. Despite the efforts of Batman to stop the violence, Shreck is abducted and taken to the sewer, where he meets Oswald Cobblepot, the gang's secret leader now known as the Penguin. The Penguin blackmails Shreck with evidence of his corporate crimes into helping him return to the surface, and he accepts. Meanwhile, Shreck's secretary, Selina Kyle, discovers the true purpose of Shreck's power plant to drain Gotham of its energy and bring the city under Shreck's control. Shreck pushes her out of a window to silence her, but she survives the fall and vows revenge, taking up the mantle of Catwoman.
