Love Battlefield 2004

To give their relationship some new excitements, lovers Yui (Eason Chan) and Ching (Niki Chow) are planning to spend their holidays together in Japan. However, Yui gives almost all his money to help his friends who are in trouble. Though furious, Ching forgives Yui at last and goes on planning their vacation. Unfortunately, Yui's car is stolen on the day they depart. They are frustrated and have a big quarrel and Ching wants to break up and leaves Yui going to Japan alone. On his way to airport, Yui finds his stolen car and a robber called Wah hiding in the truck. Knowing Yui is a nurse, Wah threatens him to help save his wounded friend while he shoots a patrolling police to death. Scared, Yui brings them to his home and stealthily takes away his walkie-talkie watch which Ching also has one. 

Wah's friend dies on the way of their operation. Wah blames Yui on it and decides to burn him to death. Ching's heart is broken when she sees a badly burnt corpse. Suddenly her walkie-talkie watch rings, which makes Ching believe that Yui is still alive. She therefore goes out and looks for Yui with her friends, knowing that she is the only one who can save Yui out of danger...
