LIN reports HUNG's case to the police. HUNG realizes that she has committed something illegal. She regrets but it is too late. She has to return to Mainland China. In order to stay with her husband so as to look after her husband, HUNG agrees to co-operate with the ICAC. She tells them that PING is the agent and she agrees to buy another travel document from PING so as to prove him guilty. The ICAC overhears PING's conversation with KI who works in the Immigration Department. However as the place is so noisy, they cannot record the conversation clearly. As it is an important chance, they arrest PING and arrange HUNG to contact KI. At last they manage to collect sufficient information and arrest KI.
