The attractive policewoman Carla Paul still has the remains of her carnival make-up and glitter on her face. But now the motto is: "Make-up off and off to work!" Because the attractive head of a small police station in the heart of Cologne is facing the biggest challenge of her life: the annual madness of the Rose Monday parade. Not only did she break up with Rick, her colleague who is still madly in love with her, just a few days ago, but today of all days, the auditor Kersten, another of Carla's exes, arrives. She and her colleagues have their hands full trying to get the drunken rabbits, chickens and Mainzelmännchen into the already overcrowded sobering-up cell at the police station.
