This was a movie that made a certain style of story extraordinarily popular.
It starts out cliched enough with the background of a happy couple separated, the wife being pregnant, by the evil bro of the rich husband. Wife gives birth to 4 babies. Bad guy who is going to kill her takes all four. She escapes.
One baby is left in a temple and picked up by a Palakkattu cook. Another is left in a car, which by coincidence gets picked up by its own father. One is left in an orphanage, and the bad guy adopts the last one.
The story, then picks up, and follows various twists and turns.
It is a very good movie, and is really funny. Great acting all around.
