Nicky Wu is Leo (gag!), an aimless hitman who’s soulful because he’s played by a little Sky King. He has heart disease so he’s due to bite it rather soon. When he wants out of the biz, his evil boss and henchman (Ma Tak-Chung) aim to take him out. Caught in the crossfire is a nice guy cop BB (
Lawrence Ng) who’s due to be married to a florist named Maggie (
Ada Choi). BB’s heart gets donated and wouldn’t you know it, it ends up in Leo’s chest cavity. The bad guys still want him dead, but he possesses a vial of deadly poison gas that they’ll all kill for. If that wasn’t enough, Leo’s heart starts doing strange things to him. He begins to take on parts of BB’s personality, and soon he’s led to Maggie.
