Knock Out (2010)

While making a call from a phone booth in Worli, Mumbai, businessman Bachubhai alias Tony Khosla, who lives with his wife Lakshmi, and their young daughter, is interrupted by a male. He manages to shove him out, but is interrupted again by another male, and when he shoves him out, this male pulls out a gun but is shot dead by a third unknown male. This third male phones Tony and tells him that he was the one that saved his life, and Tony cannot hang up the phone--if he does, he will be shot dead. With crowds, police, and the media descending on the scene, a hapless Tony will be held hostage; his personal life, including his affair with another woman, will be exposed; while the unrelenting sniper takes his time to clarify why he has decided to hold Tony in this situation.
