In this "operetta," Oil Can Harry and Mighty Mouse battle over Pearl Pureheart in an amusement park on Coney Island. Oil Can has the pretty girl tied to the roller coaster tracks, and Mighty Mouse must save her before the giant roller coaster comes and rides right on top of her! The entire story takes place at the amusement park, and includes a House of Horrors, a house of mirrors, roller coaster, "10-Cents-A-Loop Plane Ride," etc. Oil Can eventually takes the girl and locks her inside his home, then forces her to dance with him. There is a big battle between Mighty Mouse and Oil Can, involving a shootout, which plays like an opera. Mighty Mouse finally saves the girl, and the story ends in... the Tunnel of Love!
