Alex is forced to come out of hiding and take the mission to protect a Taiwanese general to Lisbon on a secret mission. He has only two rules: watch the general’s back; and never leave the general alone, live or dead.

However, Alex messes up. He didn’t warn the general not to sit besides a window in a local diner, and the general got shot. Alex now needs to carry the unconscious general, run away from the killer, and find out what exactly happened.

At the same time, Wu—bored to death with insurance claim investigations—receives a peculiar insurance claim. The company’s legal department suspected that this gunshot wound claim is not a simple case.

Can it be linked to Alex’s troubles? Wu and Alex, with their detective instincts roaring back to life, must spring into action again.
