Jakob von Gunten, a boy of unknown origin, arrives at the Benjamenta Institute, a school for servants presided over by the brother and sister Benjamenta. At the same time, the pupils introduce themselves. From the beginning Jakob claims certain privileges. The school days would be very boring, if Mr. Benjamenta himself didn’t offer Jakob his friendly affection. But can he trust him? Lisa, Mr. Benjamenta’s sister, is obviously fond of Jakob, and sings about freedom: freedom to decide – she wants Jakob to respond to her love. Rivalry develops: Benjamenta and Lisa alternately try to win over Jakob. Meanwhile, one by one the other pupils leave the institute. Lisa, thwarted and exhausted, dies and with her ends the whole institution. Benjamenta forces Jakob to decide about his life.
