Hot War is a 1998 Hong Kong thriller film directed by Jingle Ma, starring Ekin Cheng, Jordan Chan and Kelly Chen.
A group of CIA scientists, C.S. Koo (Jordan Chan), Tango One (Ekin Cheng) and Blue Szeto (Kelly Chan) are working on a secret project called "VR Fighter" which uses a combination of hypnosis and virtual reality to turn ordinary men into super fighters. A rogue terrorist known as Alien (Terence Yin) wants the hypnosis technology to use for inciting riots to drive up commodity prices, and so he kidnaps Blue. C.S. and Tango decide to use VR Fighter to rescue Blue, but during the mission they learn of the project's consequences that it turns some of the subjects into raving homicidal maniacs. The two friends are set against each other, all while Alien is bringing his plan to fruition.
