As punishment, Docheski's son Vassily (Joseph Sikora) and his men kill Wright's pregnant wife, then promise to kill anyone to whom he speaks regularly. Luke leaves his life behind, becoming a homeless tramp. Meanwhile, in China, Mei (Catherine Chan), a young math genius, is kidnapped by men working for Triad boss Han Jiao (James Hong). Han wishes to use Mei as a mental calculator to eliminate his criminal enterprise's traceable digital footprint.
