Amitabh Bachchan, Amrish Puri, Fardeen Khan, Kareena Kapoor, Milind Gunaji, Om Puri, Rati Agnihotri
Amitabh Bachchan as Dev Pratap Singh: Dev Pratap Singh is the Joint Commissioner of Police. A proud and seasoned Police Officer!
Om Puri as Tejinder Khosla: Special Commissioner Tejinder Khosla is the balancing force between the political interests of Chief Minister and Dev's commitment to the law.
Amrish Puri as Bhandarker: Bhandarker is the chief minister of State
Fardeen Khan as Farhaan: Farhaan is an unemployed law graduate. His father Ali Saheb had bought him up on his ideas of patriotism and non-violence. But his father's violent death leaves him emotionally orphaned. Dev unintentionally imparts Farhaan the wound that plunges him into violence.
Kareena Kapoor as Aaliya: Aaliya is a charming and a romantic person who is the ray of light and warmth in Farhaan's life. She gets caught in an extraordinary circumstance that transforms her life.
Ehsaan Khan as Latif: Latif is a cunning and ambitious politico
Dev is the saga of Dev and Tej's friendship…a bond stronger than blood ties in which Farhaan emerges as the wedge driving them apart. The story unfolds against the vitiated atmosphere of present times where innocent lives become fodder for political expediency. The spark of terrorist violence unknowingly set off by Farhaan under the aegis of the corrupt politician Latif engulfs the whole city in its flames. Tej transgresses beyond the boundaries of law in his passion to eliminate anti-national crime. Dev is faced with the spectre of the tragic human cost and a moral compulsion to act.
The stakes rise beyond self-interest. Dev and Tej are set on a path of dramatic collision. Even as Dev and Farhaan's fate gets irreversibly linked, two soldiers whose allegiance may be to different causes but admiration for each other's courage and integrity brings them together.
