In english, it's sleeping dog, but in german, it's schlafende hunde. A six episode arc, with two directors and three writers. According to imdb, this is a remake of the israeli series exchange principle, which had three chapters. Atlas, a former cop, is living on the streets. But has not given up trying to solve an old cold case. He breaks into offices after hours, and tries to stay under the radar. Andergast, the public prosecutor, also wants to reopen the case, but for very different reasons. Lots of mysteries and questions. Witnesses that won't come forward, for various reasons. Some are getting knocked off. They seem to be up against powerful families that stick together, and will do anything to succeed. Both atlas and andergast have people helping them and people working against them. Lots of suspense and drama. Mostly good stuff! Although one of the cops held up evidence, a hand gun, while wearing gloves. But he held the gun right where the suspect's fingerprints would be !! Bad cop.
