The story is exactly like many other similar plotted films, the one I know dated back to 1958, an Indian Tamil-language comedy film "Sabaash Meena" - Same carefree rich hero avoiding responsibilities, get away from his dad, goes after his love as a poor family guy, swap his poor background friend in his place, confusions in climax etc, etc.. But coming to the execution, this movie did mostly same as others, but messed it up in climax... why the rush? what convinced the female lead character to forgive the male lead character? It would have taken another 5 minutes of the movie to show some scenes for the hero to convince his lover to get her back, but the movie ended abruptly without caring to tell audience why she was convinced to get back with the male lead.
The movie had fun moments, good acting, familiar story line, but with unconvincing finish.
