Robert McCall is a retired secret agent. Having become disillusioned by all the rigamarole that comes with secret agenting, McCall starts to look out for the little guy. Calling himself ``The Equalizer,'' McCall puts ads in the paper marketing to desperate people in desperate situations. McCall usually takes these cases for little or no money (he lives in a posh Manhattan apartment). Acting as both bodyguard and investigator, sometimes using his government resources, McCall usually manages to save the day.
