n 1985, in Dallas, the homophobic electrician and rodeo rider Ron Woodroof is a cocaine user who frequently has sex with hookers and promiscuous women. When he has an accident at work, he is sent to the hospital where Dr. Sevard and Dr. Eve tell him that he is HIV+ and will die within thirty days. Ron also meets trans-gender Rayon, who is drug addicted and also has the disease. Ron does not accept the diagnosis but a couple of days later he realizes that it may be accurate. He researches about the disease and learns that AZT might be lethal for infected people. Further, he discovers that in Mexico there is a doctor with revoked license named Vass that uses alternative drugs in the treatment of AIDS. Ron improves his health and decides to sell the drugs in Dallas. He makes a partnership with Rayon and soon he creates the Dallas Buyers Club, where the memberships pay four hundred dollars per month to have the necessary drugs. But the FDA does not accept his research and he is oppressed by the authorities.
