After discovering a secret Chinese plot to take Taiwan, Jack James, undercover CIA agent and University English teacher, is shot and injured badly. He manages to get his cell phone to one of his students, Tony Xu, and tells him that he must take it to the US Embassy in Beijing before passing out and being captured by CIS (the Chinese Intelligence Service) in Tony's apartment. Tony involves his friend Lilly Li, and soon finds himself in a fight with a CIS agent and both become wanted by CIS. They decide the best course of action is to follow Jack's instructions and take the cell phone to the embassy.
