A private investigator and a police inspector team up to pursue a notorious mobster, who is plotting to milk an old millionaire out of his highly-valued stocks and bonds. Along the way, the investigator crosses paths with a femme fatale and silly gangsters.
Mak Kar, a faithful and honest constable, was ordered to arrest Dean Saki, a pickpocket. However, each time he was caught, he was released by lack of evidence. Although Dean was a tricky man, the money he pickpocketed from those dirty rich people was spent on the seven poor orphans with whom he lived in an old shaky church. Dean had an intention to buy a house where he could keep more orphans.
