As a director faces a series of setbacks in life including debt and divorce, his elderly father suddenly regains his youth.

A lawyer falls in love with a gang boss, gets knocked up and drags him to the altar. One evening, cradling the crying infant, he metamorphoses into a doting daddy, and henceforth devotes his life to keeping her from finding out his true identity.

In this whimsical French comedy, Cookie (aka Venus de Palma) is a tough, sweet little rich girl, and is rather smart, too. She's smart enough and charming enough to outwit her kidnappers by setting one against the other until they have all killed each other or died trying to prove thier worth to her.

The film begins with 3 happy bachelors Anand, Sudhakar, & Siva who share an apartment with frequent parties and flings. One day, a baby named Maya arrives on their doorstep with a note revealing she is the result of the perfidy of one of them. Then, Anand thinks back about his first love Sunita and they spent the night together. Later, Sunita misconstrues, loathes, and splits from Anand catching sight of his closeness with another girl. So, Anand declares Maya as his child. Accordingly, it forlorn the men to take care of the baby and attempts to dispose of her but fail as they are strongly correlated. Parallelly as a glimpse, Sudhakar & Siva love their neighbors Shanti a modern girl & Jyoti a widow respectively. Aside from this, a dreadful gangster Johnson smuggles precious diamonds on time which struck at Maya's cradle, and they back her.

Robert Langlois is now married to Catherine, the former housemaid. And they would live happily ever after if the housing crisis did not force them to live together with Gabrielle and Fernand, Robert's parents. For, despite the good will on either side, tension soon arises. What else to expect when there is too little space in their Montmartre apartment for four people (then for six then eight, the couple having... two pairs of twins!) ; the continued presence there of Fernand (who loves peace and quiet) after he is driven to retirement ; the difficult beginnings of Robert as a lawyer in a room of the apartment, etc... Other troubles follow and the harried family is on the verge of implosion...
