Perfect Couples follows three flawed pairs trying to get it right. Dave and Julia are the "everyday couple," messed up in all the "normal" ways. Dave struggles to keep both his wife and his needy best friend, Vance happy. Vance and the volatile Amy are the high-passion, high-drama couple who bring out the best and worst in each other. The third duo is Rex and Leigh. Rex is a reformed party guy who has channeled his jock energy into a competitive drive to be the ideal mate. Leigh, a self-anointed relationship guru, has formed the perfect union with Rex, and now considers it her duty to mould the other couples in their image.
