Tacky novels illustrator Rüdiger lives divorced with more then half custody of pre-teen son Max and gave up dating as parenthood scares flirters, but florist buddy Jürgen arranged a blind date behind his back, instructing to keep silent about Max. College lecturer Marlene, who didn't score a date since she got her pre-teen daughter, was similarly tricked by mate Pauli into a date with Rüdiger.
