A merchant, known as the “Rubber King”, arriving from Singapore, is confused with the identities of two comedians, Udel and Tjepot, in a newspaper report. The business partner of the “Rubber King” picks up Udel and Tjepot, while the committee takes the “Rubber King” to the Art Theatre. The situation gets complicated when someone tries to kidnap the (fake) “Rubber King” to get ransom money. Fortunately, the father of the “Rubber King” arrives to explain the misunderstanding. Udel and Tjepot, chased by the bandit, run to the theatre stage, and that’s where the police capture him.
