Vanessa and Anika, student nurses in their second year of training, look amazingly alike. But Anika is much more serious than Vanessa. Anika has other priorities that evening as well: helping instead of partying with the attractive residents in the nursing home. For more than a year she has been working in the initiative "Medics for Illegals (MefI)", which was launched by the charismatic doctor Annemarie Bindra. Here she also met the young Coptic Christian Kamal Atiya, who fled Egypt with his little brother Raouf. The brothers are tolerated in Germany. When Anika finds out that Kamalworks as a informer for the immigration authorities, the idealistic student nurse puts the pistol to his chest: either he will make his betrayal public or she will do it.
Less than two hours later, Anika arrives at the dorm. The party there is over. There is dead silence in the corridors. In her room, Anika comes across her lifeless friend Vanessa, strangled with a bathrobe belt... While Jens Stellbrink begins his investigations, a desperate Anika asks herself: Is Kamal Atiya not only a traitor, but also a murderer? "The Pact" is the last "crime scene" with Devid Striesow as Jens Stellbrink.
