In episode #1, Benno Berghammer is in his early forties. An only child and heavily overweight, he still lives with his widowed mother, Resi Berghammer (Ruth Drexel), who is running a small bed and breakfast in Bad Tölz. Berghammer takes it for granted that his mother cooks for him (twice a day: he even returns home for lunch whenever possible) and that she washes his clothes and tidies up his room but there is hardly anything he gives her in return. While she is proud of her son and his achievements at his job, Resi Berghammer does not approve of his celibate lifestyle. Longing for a grandchild, she occasionally dabbles in matchmaking when she becomes aware of an eligible female. But although her son has a penchant for attractive female suspects he never gets involved with any women. Generally, there is constant bickering between mother and son over all sorts of things big and small.
