The shy Hugo is a caretaker in a prefabricated building. He feels at home here, is appreciated by the residents and sings his songs in the corridors. Dramatic changes make Hugo uncomfortable in his home. Similarly dissatisfied is Johanna, who lives in a bus in front of the house and faces racism and sexism on a daily basis. The two grow closer – sharing a sense of not quite belonging and, above all, a love of music. For Hugo, the world is visibly coming apart at the seams: birds that reject freedom, a dollhouse that develops a life of its own – At the same time, a catastrophe is brewing in very real life that puts Hugo and Johanna’s friendship to the test.
