A high tech corporation is sent into turmoil when hackers demanding ransom break into their internal computer system with a powerful and apparently unstoppable virus. A mysterious, beautiful young woman who calls herself "Computer Angel" quickly saves the business. But when she requests a meeting with the company's shady CEO, he gets more than he bargained for. Lynn (Shu Qi of The Transporter) turns out to be a highly skilled assassin, who knocks off the CEO with the help of her rambunctious younger sister Sue (Zhao Wei of Shaolin Soccer). Sue uses a powerful computer program developed by the girls' murdered father, which uses satellites to tap into closed-circuit security cameras, enabling her to see where all the cannon fodder/guards are and direct Lynn's escape, while taking over the security team's audio system to pipe in a cover of the Carpenters' "(They Long to Be) Close to You." But things soon get dicey for Lynn and Sue. A brilliant, sexy forensics expert, Hong (Karen Mok, who also sings the film's theme song), is hot on their trail, and the creeps who hired the girls decide to cover their tracks by killing them. Complicating matters further, Lynn reunites with an old flame and contemplates giving up the business and settling down, much to Sue's chagrin. So Close was filmed in Mandarin, necessitating (reportedly poor) dubbing into Cantonese for the Hong Kong release. The film was directed by Corey Yuen, who made his Hollywood debut with The Transporter. Before that, he was best known for his fight choreography on many of Jet Li's films. So Close was shown at the Subway Cinema's 2003 New York Asian Film Festival.
