When a prisoner transport is robbed, inmate Volker Zahn is freed and a policeman is killed. From prison, Victor de Man, whom Lannert and Bootz arrested years ago, calls in and offers information in exchange for parole. In fact, thanks to his tips, they manage to free a kidnapping victim and get clues about a new big coup by the bank robber Zahn and his gang. With the prospect of being released for the remainder of his sentence, de Man promises to get more information about the planned robbery. In this way, the commissioners and prosecutor Álvarez could possibly prevent the planned crime and arrest Volker Zahn again. There's only one catch - de Man has to be temporarily released for it.
Although under the supervision of the commissioners, the risk of an escape cannot be ruled out. Sebastian Bootz is extremely skeptical. Thorsten Lannert, on the other hand, believes he knows de Man well enough and is willing to trust his promises. Tatort+: There will be a transmedia expansion for "Tatort: Spiel auf Zeit". The online investigations begin a week before the "crime scene".
