Yalan Dünya (1972)

Two brothers raised apart are locked in a life-or-death conflict. Kemal, hardened by a childhood with his mother after his parents split, has spent years in and out of prison. Upon release, he meets his grown son for the first time—only to find the boy gravely ill. The mafia, desperate to take out Commissioner Murat for disrupting their underworld order, tries to recruit Kemal. He wants to leave his violent past behind, but his son’s heart surgery demands a fortune he can’t afford.
