Love Ranch (2010) on Netflix

In the mid-70s, near Reno, Grace Bontempo runs the Love Ranch, a legal brothel. Her husband Charlie, with big dreams, a felony record, and an aptitude for spending and infidelity, is the brothel's public face. On the day Grace's doctor tells her she has cancer in an advanced state, Charlie takes on new client, Argentine boxer Armando Bruza, Charlie's ticket to fame: he hopes to promote a fight with Ali. Because of Charlie's felonies, Grace is Bruza's titular manager. With the IRS and the church ladies circling the business, Grace takes the manager's role seriously and, along the way, Bruza charms her. Secrets play out: is there love at the Love Ranch? How will Charlie respond?
