Germany, the '70s. Leopold, a smug, still-hunky 50-year-old businessman, picks up and seduces fresh-faced, carrot-topped 19-year old Franz who swiftly moves into his bachelor pad. Their cozy relationship soon sours as Leopold, a kind of gone-to-seed Dirk Bogarde, turns cranky and argumentative. When Franz's buxom blond girlfriend surfaces, and then Leopold's elegant and enigmatic ex, things get funnier, steamier and a lot more complicated.
