Its revealed that Valentina (Natalya Rudakova) is the daughter of the Enviromental Protection Agency Leonid Vasilev (Jeroen Krabbe). Leonid is being forced by Johnson (Robert Knepper) to bring in toxic waste. Frank Martin (Jason Statham) is forced to bring Valentina to Johnson. Johnson tells attempts to kill Frank. Even when he is drowing the stays with the car because if steps more than 75 feet from the car the wrist bomb will explode. Frank then sets his car on top a moving train to rescue Valentina. From there Frank kills Johnson.
