Sniper(2010)

Overview:

Oleg Nazarov is a captain of a special forces unit, a sniper. But his family and friends don't know about it. Oleg carefully hides his true profession from his wife and daughter, and every time he returns from a mission, he puts on the mask of an ordinary person. Meanwhile, the city where Oleg lives is in a state of panic. The reason for this was a series of murders - every day one person is killed by an unknown gunman.
