Mujhse Shaadi Karogi

Sameer (Salman Khan) is a hot-tempered person with terrible anger management issues ever since his parents died in his childhood. After he beats up a group of goons who tried to assault his girlfriend Roma (Amrita Arora), she breaks up with him due to his bad temper. Thus, as per his horoscope, he is very unlucky in love. With a heavy heart and in order to get away from everything, he leaves for Goa to take up a job as a lifeguard.On the train to Goa, he meets a man named Suraj Prakash (Satish Shah).

He lures Sameer into believing that he could be a thief by asking him where he kept the more important things, such as money, in his luggage. Sameer ends up staying awake the whole night in order to avoid being robbed while Suraj Prakash sleeps peacefully the whole night, having conned Sameer into guarding his own luggage. This is also something he admits to Sameer the next morning at the station in full overconfidence. Sameer later finds out that the former is a security guard at the very resort he is working in and had retaliates by putting Suraj Prakash on guard duty for night times for 3 months, with the threat that he would lose his job if he ever slept even a wink on night duty. This causes Suraj a lot of trouble since he has never done night duty before and instead devotes night times to spending quality time with his wife.

Having had a taste of his own medicine, he tries to desperately apologise to Sameer, later even with the help of his wife, but Sameer does not relent.In Goa, he meets Rani (Priyanka Chopra), an upcoming fashion designer and instantly falls in love with her. After many attempts at befriending her and a rough start with her father, (Amrish Puri), a former colonel in the military, Rani and Sameer become friends. However, Sameers ill fated luck comes into play as he still has some rough incidents with her father and Rani, too gets angry with him since she overhears him saying bad things about her to Pandit ji (Rajpal Yadav).Further trouble arrives in the form of Sunny (Akshay Kumar), who moves into the same house as Sameer and shares a room with him.

He too meets Rani, falls in love with her and decides to cause further trouble by getting closer to her through the mistakes Sameer makes. This causes a lot of trouble between the two. It is evident that Sunny is out to ruin Sameers relationship with Rani so that he can steal Rani away from him. Sameer helps Rani with money that she urgently needs for a fashion show, but makes the mistake of calling himself her well-wisher while doing so. Rani wins the fashion show and while being felicitated for her victory, makes an open offer to her well-wisher to meet her so that she can thank him in person.

Sameer, who had selflessly given Rani the money which he was supposed to pay for both his grandmothers eye surgery and his sisters wedding, goes to meet her but Sunny gets there first and claims to be the well-wisher and takes her away with him. Sameer follows on his motorcycle and ends up injuring the colonel severely. Sunny goes to the extent of taking credit for a painting of Rani that Sameer made. He kidnaps Ranis dog, Tommy and blames Sameer for it. Sameer buys an identical dog from a pet shop and goes to the colonel, claiming that he has found Tommy.

His ruse is later discovered by the colonel when the dog bites him and runs away.These actions aggravate Sameer and ignite his temper, making his relationships rocky, but he somehow manages to reconcile with Rani with the help of a magician at a New-Years eve party. Sunny strikes back by conveniently placing a bar dancer in Sameers room one morning. Rani who happens to go there to invite him for breakfast, sees the dancer there and assumes that they had sex, eventually not heeding to Sameers frantic pleas of innocence and walking out in tears.After the fiasco with the bar dancer, Sameer still decides to make another attempt at apologising.

When he goes to Ranis house, he is surprised to see Suraj Prakash there and is shocked to learn that he is Ranis uncle, who now knows that he loves Rani. He tries to clear the earlier misunderstanding by apologising for his indiscretion and taking Suraj Prakash off night duty. Also another misunderstanding occurs when Sameers grandmother who is partially blind arrives and mistakes Ranis mother for Rani while trying to persuade her into marrying Sameer. Sameer, who goes to sort out the situation gets caught in an embarrassing position with Ranis mother. Rani, who is shocked and disgusted is later advised by her mother that Sameer had not been at fault in that situation.

She also says that Rani should carefully deliberate on whom she loves more- Sameer or Sunny.Disgusted and completely out of hope and patience, Sameer decides to leave Goa forever. As he is leaving, Sunny arrives and taunts him on how he got close to Rani through the latters mistakes. Sameer says that he has had enough of dreaming of Rani and wishes Sunny all happiness as he leaves. Sunny however tries to have the last laugh as he taunts Sameer again.

This time, Sameer loses his temper completely. He rounds on Sunny and chases him through the streets right through to a crowd at a cricket stadium, where India and Pakistan are supposed to be playing a friendly match. Deciding to have one last try, he enters the field after breaking through security, takes the mike from Kapil Dev, the guest of honour, and uses it to apologise to Rani and her parents very sincerely for his past mistakes. Saying so, he confesses his love for her and asks her to marry him in front of the whole crowd, coupled with motivation from spectators and players alike. Rani runs out to the field and embraces him, thus reuniting with him.

At the end, Sunny arrives and reveals that he is actually Arun, Sameers childhood friend who had come to Goa, for a cure to Sameers anger management issues. He had gone to visit Sameer the first thing after coming back from America after 19 years and had met the latters grandmother, who had told him about Sameers heartbreak and subsequent departure for Goa. At that point, he had decided to help Sameer, but by posing as his enemy. He had revealed the same to Rani and her parents earlier. Sameer is then reunited with his old friend as well.

The film ends with Arun conducting Sameer and Ranis marriage.
