The movie is filmed in the style of a stage pantomime, with over-the-top comedy and featuring the characters occasionally breaking the fourth wall.

Zain) and Labi (P. Ramlee) are servants in the household of Haji Bakhil, a miserly old man with a loyal wife and a beautiful daughter (Mariani).

Both Labu and Labi are constantly scolded, insulted and forced to do the traditional school punishment ketok-ketampi by the grouchy Haji Bakhil.

Labu and Labi watch a performance by Saloma who sings the song Bila Larut Malam with her husband P. Ramlee providing back-up vocals.

The film returns to the "real world", where Labu and Labi are loudly fighting over Sarimah, waking up their boss, Haji Bakhil, who shouts at them to go to sleep.

Labu and Labi eventually start a gunfight in the imaginary bar, and their gun sound effects wake their boss up for the third time.

Haji Bakhil refuses, and as retaliation Labu visits a bomoh (magician man) who casts a spell on Manisah, causing her to fall into a coma.

Witnessing this turn of events, Labi visits a magician man of his own, who gives him a magical stone that, when dropped into any water, causes the liquid to have healing properties.

On the day of the wedding, Labu arrives at the house and casts a spell that causes everyone to fall asleep except for Labi, who uses his magic stone to wake up Manisah.
