57-year-old Hilde likes to lead the way - both in her family and at work. That's why she regrets having failed with her own restaurant years ago. Now she may be making her umpteenth new start at the Quincy's burger chain, but she remains true to herself: she only sticks to rules that make sense to her! When Hilde is dismissed by the branch manager, her own son Tommie, she puts all her eggs in one basket: together with her two friends, whom she already had on her team as canteen manager in GDR times, Hilde wants to take over the sports hall and offer home-made burgers there - not ordinary hamburgers, but "McLenBurgers"!
