Le Corps de mon ennemi (also known as Body of My Enemy [2]) is a 1976 French crime film directed by Henri Verneuil.

Through the budding relationship with her in-laws, Leclercq is able to assimilate into the local upper class of his hometown, Cornai.

A friend of Gilberte's father, Raphaël Di Massa hires him as manager of his new nightclub, "Number One".

The oblivious parvenu Leclercq eventually discovers that "Number One" is actually a cover-up for Raphaël Di Massa's illegal drug trade.

Seven years later, he returns to Cornai and discovers that it wasn't Di Massa, but Gilberte's father Jean-Baptiste Beaumont-Liégard who ran the drug operation during Leclercq's employment.
