In modern days, there lives an assassin who will do the dirty job for people who are willing to pay required sum of money. As he is one of the best, he does not have a lot of work to do. He lives in apartment in block with poor people so he does not attract a lot of attention. Everything goes the other way when in apartment nearby come drug dealers to kill everybody related to one of their coworkers who made a mistake. Young girl passes by her apartment and sees that all of her relatives got killed and goes to the door where she is expecting neighbor to let her in. He thinks a lot about it, but lets her inside so she does not get killed. As they start living together, she presses him on and on to teach her how to become one of the assassins. It took too long, but he started working with her. At the end, to make her revenge, she had to find people who were responsible for death of her family and kill them too. During this final fight, her mentor (Leon) gets killed, but he takes with him all of those responsible with him.
