Keep Calm and Be a Superstar
As a huge fan of Hong Kong cinema, Tiezhu from China dreamed of becoming a cop like in the movies. Unfortunately, he fails the fitness exam in China’s Police Force selection because of asthma. So Tiezhu settles for the next best thing which is working as a private investigator (PI).
One day, while on case, he is forced to go undercover to investigate the international action movie star, Pau, who is Tiezhu’s hero! According to a tip-off, Pau has been interacting closely with the renowned Thai drug lord, Eight-Faced Buddha, and they are suspected of using movie-making as the front for trafficking.
Determined to clear his idol’s name, he accepts the mission and starts investigating by joining the film crew. As Tiezhu gets closer to his idol, he realizes that Pau’s fierceness and talents are all movie magic, while the real Pau is a normal man without the wisdom and kung-fu skills like the characters he has played.
After finally getting a supporting role in Pau’s movie, Tiezhu discovers the big secret behind Pau’s dealing with the Eight-Faced Buddha and his cover is in danger of being blown.
