Blind ex-cop psychologist Tom Leschek applies with Dutch-born therapist Jessica van der Laan for a job in her Berlin practice, probably unsuccessfully, they go shopping and happen to witness how SWAT cop Martin Buchmüller goes berserk in a supermarket, heavily armed, taking witnesses, accompanied by his frightened teen brat daughter Kathrin. Although the incompetent chief opts for waiting for a regular negociator, Jewish SWAT team leader Dr.Richard Rosenzweig insists to make use of "Alphamann" Tom in front on site, with Jesscia as back-up by phone. Martin refused to accept custody of his daughter being awarded to workaholic mother Caroline and her new partner, lawyer Mark Zumboden and knocked down his SWAT colleagues who were court-ordered to take Kathrin away. Caroline grudgingly comes when demanded by Martin, but hardly follows Tom's instructions.
