A girl from a wealthy family, daughter of the ambassador to Spain (Momoe Yamaguchi) is surprised by some yakuzas who attemp to rape her, but fortunately for her, a thug from the neighborhood (Tomokazu Miura) appears to save her stealing her heart in the proccess… However, They both come from very different backgrounds and worlds apart, and their love will not be a bed of roses, but rather a bath in the mud.
Directed by Sokichi Tomimoto, Love in The Mud (1977) was the second adaptation of a novel into cinema, and one of the many films that Momoe Yamaguchi and Tomokazu Miura starred together and in which they forged their love off the screen, until they got married and she retired forever from show business to dedicate herself to her family, leaving her big fandom waiting for a return that never happened.
Love in the Mud is a title that perfectly defines the film, a tragic love story where social classes play an important role, and the romantic idea of rich girl loves poor boy is a blind bet on a loser horse that rarely goes well.
Throughout the film we accompany Momoe´s character through the City of Tokyo in search of Miura, in an obsessive quest of love with which she seems to want to escape from the golden cage in which her family has trapped her, however, he doesn´t seems to believe in such hopeless dreams, with more maturity and some stabs more in his body as vital experience, he is not fooled by any false hope, and despairly tries to open the eyes of the naive girl. But spoiled bratts never give up to pursue their whims, and the girl will not give up pursuing her romantic dreams, in addition, her family also looks for a way that this love, which for them is nonsense, never becomes consolidated.
A sad love story, as real as life itself, where what should have been and never was, becomes the memory of love stories that dared to defy the unwritten rules of society. A love that arises from a stab, can only end in the mud.
