Plot
In Edge City, insecure bank teller Stanley Ipkiss is frequently ridiculed by everyone except for his co-worker and best friend, Charlie Schumaker. Meanwhile, gangster Dorian Tyrell, whose boss Niko owns the Coco Bongo nightclub, plots to overthrow Niko. One day, Tyrell sends his dazzling singer-girlfriend, Tina Carlyle, into the bank to record its layout for an upcoming robbery. Stanley is attracted to Tina, and she seemingly reciprocates.
After being denied entrance to the Coco Bongo to watch Tina perform, Stanley's faulty loaner car breaks down during his drive home, leaving him stuck on the harbor's bridge. Attempting to rescue a humanoid figure in the waters, he finds a pile of garbage concealing a wooden mask. Upon returning to his apartment and donning the mask, he transforms into a green-faced trickster known as "The Mask", who can cartoonishly alter himself and his surroundings at will. With newfound confidence, Stanley indulges in a comical rampage through the city, humiliating several of his tormentors, including his temperamental landlady, Agnes Peenman, and the mechanics who gave him the faulty car. Meanwhile, Niko learns of Tyrell's plans and warns him to leave Edge City in one week or be killed.
