"It's a comedy series about the impossibility of being happy with someone of the opposite sex, because it only gets funny when it really hurts." That's how writer, director and leading actor Michael Niavarani describes the idea behind "Ex - a romantic comedy." At the center of the plot is 43-year-old, sex-obsessed Philipp, who (for the umpteenth time) is on the verge of failing in a relationship because there's one thing he just doesn't get: What really moves the women in his life.
