The doctors, nurses and carers of the alpha team are the first to come to the aid of the people in the Hansa clinic. There is often too little time left for the private life of the emergency room crew. That night, they’re holding the breath of three victims of a shooting. Street boy Timo (Max Riemelt) is proud that he was allowed to exchange blows with his idol, the well-known criminal Krupp (Frank Wieczorek). Both were seriously injured and also the guard Bokel, whom Krupp shot, is not doing well: internal bleeding and an injury of the spleen. Dr. Scheu (Hermann Toelcke) operates and helps the young colleague Sturm (Matthias Scherwenikas) to take his first steps in the operating theatre. But the operation on Krupp puts Dr. Brandt, Dr. Bennacef (Francois Smesny) and Dr. Voss (Herbert Trattnigg) themselves in mortal danger: „The wound contains a rifle grenade.“
