Former CIA agent, elderly African-American Robert McCall, has decided to start his life anew, leave his troubled past behind and look to the future, just as he promised his late wife. He has already found a regular job as a store clerk. One day, McCall stands up for a young prostitute, Teri, with whom he has been chatting at a local diner and who is under the control of the Russian mob. McCall ends his voluntary retirement and begins his own quest for justice. All those who suffer from criminal masterminds, corrupt officials and cannot find help from the state find help in the person of McCall. He will help. Because he is the great equalizer.
