Set in the chaotic power vacuum left in the Gotham underworld following the fall of the Joker and the Dent Act, "The Penguin: King of Gotham" is a gritty mob drama. Oswald Cobblepot is not a sewer mutant, but a deformed, outcast scion of a fallen wealthy family. He is the manager of the "Iceberg Lounge," a front for money laundering used by the powerful Falcone Crime Family.
Tired of being called "The Penguin" and treated as a freakish lackey by the mob bosses who look down on him, Oswald orchestrates a complex, bloody war between the Falcones and the Maronis. Using his brilliance, brutality, and a terrifying comfort with violence (using his signature reinforced umbrellas as disguised weapons), he systematically dismantles the old guard. The film is a character study of a man fueled by an inferiority complex who decides that if society sees him as a monster, he will become the monster that runs the city.
