This Italian black-and-white film, based on a true story, was originally made for television. It concerns the life and sad end of Evariste Gallois (Mario Barriba), a brilliant student mathematician whose republican politics and hot-bloodedness resulted in his death; it is unclear whether he died by political assassination or as a result of a duel.

A young man returns to his village, and with the help of a black-clad stranger, seeks revenge for the murder of his brother against three men who are now notable men of the town.

Lucita has been locked away in a convent by her family in order to keep her away from her lover, Esteban. The pair make plans to elope, but Esteban is accused of heresy before Lucita can escape. Hiding in the convent, Esteban discovers the horrifying depravity of the covent's abbess, Sister Incarnation. Can Esteban rescue his love from this madhouse before the inquisitor discovers what is going on and has everyone executed?
