Sex, Lies, and Videotape (1989) on Netflix

John and Ann Mullany, a junior partner at a law firm and a housewife respectively, are a young, upwardly mobile couple, who most would deem to have a perfect life. Ann's outward perfection belies the fact that she is in therapy, dealing with the stress over worrying about global issues with which she has little to no control. She does not see certain things with which she does have control being problems in her life, namely her sexual repression or her disinterest in sex as an activity, that is until it manifested itself in this stress which in turn is having, what she believes, a negative impact on her marriage. What she is unaware of is that, long before her stress began, John embarked on an affair with her sister, bartender Cynthia Bishop, who she doesn't admire as being too "loud". John reconnects with a close friend from college named Graham Dalton, who, to John, appears to have lost his way in life in the years that they have not been in touch. Graham, via the method in which he deals with his emotional and sexual problems - which is also believes is being totally forthright to all concerned - has a profound effect on Cynthia, John and Ann, who in turn, especially Ann, have a profound effect on him.
