Vijay (Kishore Kumar) is the good-for-nothing son of a rich industrialist, who becomes bored of his father’s constant railing and the efforts to marry him off, with the intention of getting him "settled" in life. So Vijay walks out of his home and decides to leave for Bombay and start life afresh in the big city, but he doesn’t have enough money to get himself a ticket!
Vijay gets a burst of inspiration from a plump child called Munnah, who is waiting in line with his mother (Tun Tun), and decides to pass himself off a child in order to get the eponymous half-ticket.
The rest of the film follows Vijay's exploits as he avoids capture by the diamond smuggler and his girlfriend (Shammi), romances Rajnidevi while avoiding her auntie-ji (Manorama), and reunites with his father.
