Sonja Spitz, the proud owner of a delicatessen and restaurant, is on the threshold of a new phase in her life: Now that her three children have left the parental nest, she finally wants to enjoy time with her boyfriend, the younger Italian Michele. They have been a couple for some time, but Sonja has kept their relationship a secret from her children until now. Now she finally wants to admit her love and is looking forward to a new, free life. Unfortunately, the romantic togetherness doesn't work out, as Sonja's offspring return to "Hotel Mama" one after the other. As if that wasn't enough, one day Sonja's ex-husband Willi arrives at the door with his young daughter and asks for shelter. A delicate balancing act begins for Sonja: she has to tame her illustrious family ties and at the same time keep poor Michele happy with secret meetings. Of course, it's only a matter of time before this game of hide-and-seek is exposed.
