After a series of mischievous adventures with Qin in Bangkok, Tang is pursued by police as he is the main suspect in Sompat’s murder, being the last person to enter and leave Sompat’s workshop where he was murdered. Tang seeks the help of Qin, who turns out to be a prodigy in solving crimes from the knowledge Qin garnered as a mystery novel lover. During their exodus from the pursuit, Qin and Tang are captured by Sompat’s cohorts who wish to locate the now lost gold. Qin and Tang, now wanted criminals, are eventually able to escape and hide in the home of Xiang, Tang’s landlady and the #1 beauty in Chinatown. However, they are followed by the gold robbers, who arrive just before Kon’s meeting with Xiang in the same home, leading to an awkward confrontation between all parties.
Qin later finds out why Tang is implicated: on the day of the murder, Tang received a call asking him to deliver a boxed Buddha statue from Sompat’s workshop at midnight. The pair, after deciding to stay in Thailand and risk their lives, goes to the parking lot.
