Josh Engel (Mickey Hardt) owns a martial arts gym. Despite working daily with blows and blows, his life is calm and peaceful, as he prefers to focus on the peaceful and poetic side of the Eastern philosophies that form the basis of fights. Therefore, he is a kind of "guru" for the city's children. However, everything changes in Josh's life when Lisa (Maria Petz) is taken hostage during a criminal action. Negotiations between the bandits and the police become more tense with each passing moment. Commissioner Jackie Winter (Susanne Hoss) and her partner Mehmet Schulz (Ercan Drumaz), from the anti-crime division, have no other option and enlist the help of Josh, also known as Der Puma. It is in this extreme situation, disturbed by the tension of seeing her one step away from death, that Josh will be forced to use all his knowledge and techniques to try to save Lisa's life.
