After Jack Bauer and his team illegally raided the Chinese consulate, the American government claimed that an Asian terrorist group was to blame. During the raid, Consul Koo Yin was accidentally killed. Jin assisted the head of security Cheng Zhi, with acting consul Su Ming, in researching the camera evidence of the raid. Cheng noticed that one of the invaders was unmasked briefly, and had Jin research the identity of the man with officials in China. Jin soon reported to Cheng that the man was Howard Bern. Cheng then went to CTU Los Angeles to investigate the lead.
