Nayagan (2008)

Dr. Sandhya Viswanath (Sangeetha) is kidnapped from her home by a gang and taken to another location, where she is questioned about her husband's whereabouts. Though the phone in her room is smashed by the gang's leader (Anandaraj), she manages to put together enough broken pieces to make random calls. One of her calls reaches Sakthi (Ramana), who has his own set of problems since he is on the run after eloping with his uncle's daughter Divya (Keerthi Chawla). Initially reluctant, he agrees to help Sandhya and drops the phone off at a police station. The cop Guru (J. K. Rithesh) talks to her but is distracted by another problem, and so Sandhya has to bank on Shakti again.
