In the Semperit tyre factory, the only strike after World War II takes place in May 1978, lasting for three weeks. The film shows the course of the strike in interviews, photos, graphics and talks at a pub; it draws attention to the position of the union between its loyalty to the workers and its responsibilities towards the entrepreneurs.

Based on material that emerged during the occupation of the arena in the summer of 1976, the film shows the organization of collective work, the negotiations with the city and community and finally the demolition of the buildings.
