Just as the title of the movie suggests, the husband is 49 and the wife is 50. With full breasts, a beautiful face, a perfect figure, and a firm bottom, yet the husband still goes out to "cheat," perhaps he is bored with rice and craves pho. He asks for a day off work, and as soon as he leaves the house, the man calls to arrange to pick up a beautiful twenty-something girl. However, at home, the wife is not to be outdone; she also calls her lover, who just happens to be her cousin. Indeed, this couple is a perfect match, both husband and wife are debauched and have a mutual inclination for "infidelity"...
