A man learns being an avenger for good is tougher than it looks in this independent thriller from filmmaker Chris Chan Lee. After his best friend, Joon (Leonardo Nam), a small-time dope dealer, is murdered during a shakedown by gangsters, Sam Kim (Sung Kang) leaves the United States and spends a year in Singapore, trying to sort out his emotions. Eventually Sam decides to return to America with two goals in mind -- bring down the thugs who killed his friend, and patch things up with Vera (
Kelly Hu), his estranged girlfriend. With the help of underworld kingpin Don Osa (
Tom Bower), Sam sets out to get justice for Joon and make up for the pain caused to his friends and associates by his absence. However, Sam doesn't know as much as he imagines about life on the wrong side of the law, and as he deals with career criminals, corrupt police officers, and the drug trade, he is thrust into greater danger than he ever imagined. Undoing was screened in competition at the 2006 Los Angeles Film Festival. ~ Mark Deming, All Movie Guide
