Adalet Oyunu.

Retired criminal court judge Sezgin loses his faith in justice and his profession after his daughter Belgin, who was his lifeline, is murdered and his son-in-law İlker, who was tried as the defendant, is acquitted. He moves away from the city he lives in and settles in a coastal town. Although İlker was acquitted in court, Sezgin believes that his son-in-law killed his daughter. Determined to seek justice in his own way, Sezgin kidnaps İlker and imprisons him in a cell he had built in the basement of his villa. He decides that his son-in-law will remain there until he dies. His retired judge friends Fuat, Nedim, Erdal, and his wife, prosecutor Nazan, visit him a few times a month to keep him company. Sezgin's decision to close his daughter's case file, his sudden move from Istanbul, and his son-in-law's disappearance around the same time raise suspicions among his friends.
