Viett, managed to escape through a window in the prison library from the women's prison along the Lehrter Straße in West Berlin where they were being held at the time. Berberich's three fellow-escapees were members of the 2 June Movement. To an outsider, the RAF and the 2 June Movement were broadly similar both in their ideals and in their methods, but at this stage they were still separate and on occasion saw one another as rival organisations. Nevertheless, it is clear that during her time in prison Monika Berberich had already formed an excellent mutually supportive friendship with Rollnik. In a trial that took place four years later it was stated that by the time the four women had made it across the roofs to their get-away car, they had overpowered their guards: implements used in the escape had included the tube from a roll of toilet tissues, three bed springs tied together and a fire arm or fire arm replica. Berberich was recaptured two weeks later. She was making her way along the Kurfürstendamm in West Berlin to a meeting when she unexpectedly met her brother and the two stopped to chat. Monika Berberich was large, with a strikingly unusual face: as she chatted with her brother she was spotted and recognised by a passer-by who alerted the police. Arrest followed swiftly. (Berberich's three fellow-escapees remained at large for another two years.) Following her brief escape Berberich's sentence was extended. In the end she remained in prison till March 1988. Except during the two years 1976-1978, she shared the experience with Gabriele Rollnik, in many ways a political soul-mate, who also became a friend. During their time in prison the women took part in a number hunger strikes. The objective was to secure improved treatment and conditions. Examples included use of a cell with a window, longer exercise periods in the yard and, more generally, anything "anti-state". From experience the inmates found that up to a point hunger strikes worked. Berberich engaged in nine hunger strikes: Rollnik in six. In the end, Rollnik began to hallucinate and "hear voices". After her release she suffered continuing problems with vision and balance which she attributed to the hunger strikes. Berberich's physique seemed to deal with hunger strikes better than Rollnik's, though after her release it became clear that even she could no longer take her former robust health for granted.
