The story follows Aarush, (Akshay Kumar), a panauti (an unlucky person), who works in bar and gets money as people lose games of poker. After being rejected from getting married by a girl he goes to London to stay for some time with his best friend, Bob (Riteish Deshmukh) and his wife, Hetal (Lara Dutta), both working at a casino owned by Kishore Samtani (Randhir Kapoor). Although at first Hetal is displeased with Aarushs presence, he proves to be a kind-hearted man looking for a family. Bob and Hetal decide to get him married to their boss daughter, Devika Samtani (Jiah Khan). After the marriage, on their honeymoon in Italy, Devika leaves him for her longtime American boyfriend Benny.

Aarush decides to commit suicide by drowning in the sea but is saved by a Telugu girl, Sandy (Deepika Padukone), who he kisses when she tries to make him breathe.Sandy originally thinks Aarush is a pervert but when Aakhri Pasta (Chunkey Pandey), the owner of Italys biggest hotel where Aarush was spending his honeymoon with Devika, tells Sandy that Aarush is a widower, she befriends him and slowly falls in love with him. What she doesnt know is that Aakhri Pasta was only joking. She then finds out his wife is alive and leaves him, but later when Aarush manages to clear the confusion, she accepts him.The only way Aarush and Sandy can get married is by convincing her elder brother, Major Krishna Rao (Arjun Rampal), a strict Indian Military Intelligence officer who loves his sister and is over-protective of her.

Meanwhile, Hetal lies to her father, Batuk Patel (Boman Irani), that Bob owns a mansion and they have a child. On the other hand, Sandy tells her brother that Aarush is quite well to do too. The four are then forced to rent a mansion to make Hetals dad believe that Bob owns it. Confusion prevails and somehow Batuk accidentally believes that Aarush is married to Hetal, and Bob is the cook. Then, Krishna turns up earlier than expected, much to Aarushs horror, leading to more lies and the two couples making him believe that Aarush owns the mansion.

For half of the term, the four must pretend that the mansion is owned by Bob, and the rest must pretend that Aarush owns it. An overly suspicious Krishna sees Bob and Hetal working at the casino and uses a lie detector to find the truth. After Sandy objects, Krishna apologizes and agrees to Aarush and Sandys marriage. The whole family is invited to the Royal Palace to see Krishna get rewarded by the Queen of England. While this is happening, two workers, Santa (Suresh Menon) and Banta Singh (Manoj Pahwa), are meant to be installing air conditioning gas for the place.

However instead they accidentally supply the hall with laughing gas causing everyone to break into an outburst of laughter. During this laughter, the truth is let out but no one seems to be in the right state of mind.The two workers meanwhile stop the gas from spreading everyone comes back to their senses. Aarush is still telling Krishna the truth, leading Krishna to break off Sandys engagement. However, after Sandy tearfully pleads with him, Krishna lets the two get married.

In the end, Hetal and Bob live together with Batuk Patel, and Aarushs luck changes for the better.
