The melodramatic story of a widow, Marie Paradis, as she becomes an elderly dependant. Taking charge is her daughter-in-law, the cruel and stingy Céleste. Marie answers to all the stereotypes of the traditional mother: she's generous, loving.

A convict on the run returns to his native village to see his daughter again, who believes him to be dead. The priest intervenes to avoid a scandal that would reflect on the young girl on the eve of getting married.

A widower is struggling to raise his five children, when he finds a rich brother who imagines he will make them happy by unwittingly destroying their modest projects. After many disasters, the uncle will be more understanding and repair his wrongs. A duel to finish: moral values ​​and love against money and selfishness, in the Quebec of the 1940s.

Filmed in French, this Canadian film was based on a popular Quebec-based radio serial. The man of the title is miserable miser Seraphim (Hector Charland). Misanthropic to the point of insanity, Seraphim takes great pleasure in destroying the lives of everyone with whom he comes in contact. His current target is Alexis (Guy Provost), the ex-lover of Seraphim's long-suffering wife Donalda (Nicole Germain). Taking into consideration its daytime-drama source, it's understandable that Un Homme et Son Peche is plotted and paced like a soap opera. Star Hector Charland had previously spent 10 years portraying Seraphim on radio, so he's got plenty of "mean" at his disposal for this big-screen spin-off.
