The film takes place at a fictional petrochemical plant. There are very disorganized working conditions caused by incompetent officials, faulty plans, material deficits and delinquent behavior. One of the main characters, Hannes Balla (Manfred Krug), works on the plant and is seen as the masculine head of his crew, the Ballas. He and his crew are delinquent and often steal materials from other groups of workers to finish their own projects. Balla is seen as an uncooperative, but talented carpenter. In one of the films' famous scenes, the Ballas skinny dip in the duck pond in a nearby town and a police officer instructs them to get out. The Ballas instead pull the officer into the pond with them. Such blatant disregard for authority is one of the main problems at the plant. The Socialist Party (SED) sends a married secretary Werner Horrath to oversee the plant and tame Balla's delinquent actions. Around the same time, Kati Klee (
Krystyna Stypułkowska) arrives at the plant as an engineer who is first discouraged from working in an all-male environment. Balla does not like the Party control and in one important scene, Balla and Horrath play an aggressive clapping game, which eventually results in Horrath being pushed to the ground. Klee sees this and ultimately chooses Horrath to have a relationship with, though Balla has also been pursuing her. The three characters develop a love triangle against the backdrop of Socialist Party politics and the pressure of completing the construction of the plant on time. One of the main themes of the film is the problems that face the plant under socialist rule and how each character is affected by the Party's morals. The romance between Klee and Horrath flies in the face of Party dictates, and the turning point occurs when Klee becomes pregnant by Horrath. The pregnancy causes turmoil in the Party and results in the Party trying to clean its ranks of the "morally defective." An executive meeting is held to review Horrath's performance. They discuss his contributions to the plant as well as his promiscuous personal life. In the end, Klee and Horrath end their relationship and Horrath loses his rank in the Party and his job. Klee leaves the plant, realizing the negative effect that its environment had on her. Balla, who has matured greatly since the beginning of the film, has become a much more disciplined socialist citizen. Socialism is both criticized and praised in the end of the film. ==Cast==
