Busy London station. Delayed train from Birmingham. Two strangers waiting for the train... Rikki Thukral (Abhishek Bachchan) born in Bhatinda, living in London; and Alvira Khan (Preity Zinta) more Brit than the Queen herself, however with Lahori blood in her veins.

Crowded café. One table to share. Two hours to kill. Perfect setting for the start of a love-story. Hitch? Both Rikki and Alvira are engaged and have come to pick up their fiancés who are coming by the same train. To kill time, they end up telling each other their “how I met my fiancé” stories.

Rikki met his fiancé Anaida (Lara Dutta) at The Ritz (Paris), the same night that Princess Diana and Dodi walked out of the hotel and into the paparazzi. As Rikki says, “When two lovers die, another two are a born”. They dance... they sing... they're in love!

Alvira, a princess by nature discovers her prince at Madame Tussaud’s. When a gigantic wax model of Superman falls from the ceiling, Alvira is a sitting target. But Steve the Prince (Bobby Deol), a lawyer by profession saves her life but steals her heart! They also sing, they also dance and they also fall in love...

Stories unfold, time passes, the two strangers start enjoying each other. That Alvira is a Pakistani Brit and Rikki originally from India... that Rikki is crooked, earthy, and rakish: dabbler in various businesses; that Alvira is prim-n-proper, wannabe blue-blood, stiff upper-lip: Asst. Manager at House of Fraser’s... none of these details matter. They have gotten alarmingly attracted to each other!

Their brief encounter has created a complicated quadrangle... Rikki Thukral and Alvira Khan have gotten themselves and Steve and Anaida into a lovely mess... To get out of it both of them bend over backward, thinking quickly on their feet, dancing around each other’s emotions... After all when you’re playing musical chairs with love, there’s nothing you can do but... Jhoom Barabar Jhoom (Dance Baby Dance)!

Abhishek Bachchan as Rikki Thukral
Baadshah of Bhatinda, now Sultan of Southall... Rikki Thukral! Confront him and he pulls out his most lethal weapon... "I got class"... Can't mess with Rikki after that. Classy he is, in his own earthy way... Just watch him engineer a deal... selling pirated films, illegal antiques, rented property, second hand fridges... if need be even the Queen's crown... Rikki makes it look like a cakewalk with his canny cheekiness and charm. Rikki came to Southall with a dream...of acquiring windfall riches. He would do all it takes... The moment he met Huffy Bhai it was like love at first sight. It didn't matter that Huffy Bhai was from Karachi or that he would lift his kurta at the most inappropriate moment... they got on like a house on fire. Him and Huffy live life with the attitude and spunk that shouts out, "We're here now... and now that we're here, Southall is ours!" ...

Lara Dutta as Anaida Raza
Anaida Raza is the sizzling nymph with a soft core. Brought up in the City of Love as a pragmatic, rooted and razor-sharp woman... Assistant Manager at The Ritz Hotel in Paris... she runs her beat with metronomic efficiency and keeps everybody including her staff happy. She's dealt with all types and can be as friendly as she can be foxy. She'll manage a huge hotel and make it look like a breeze...despite thousands of photographers jumping all over the place... but also find the time to pick up Rikki's handkerchief from the floor and return it to him... How was she to know the hany would turn out bait... and she'd be hooked, in love with Rikki in the flicker of a moment.

Bobby Deol as Steve Singh
Steve Singh is the immensely rich and treacherously handsome joint partner of London's reputed Singh & Smith Law firm. Steve is the man's man... the man about town... powerful, intense and very self-effacing... Born to a British Mum and Punjabi Dad, he's a balance of Punjabi impulse - not thinking twice before heroically saving Alvira's life - and he's got suave ritzy genteel from his Brit Mum. Classy. Seemly. Chivalrous. That's Steve. He has a palace for an office matched only by Mandrake's Xanadu. And wears those dashing suits and up-market cuts like Bruce Wayne.

Preity Zinta as Alvira Khan
Picture a three foot six inch girl. She stands alone in the middle of a church. Merely six years old, Alvira Khan takes an oath before God. "I'll never marry a brownie kaalakalutaa. Please find me a good-looking gora boy like yourself. Amen." Cut to 20 odd years later. Alvira is your typical Pakistani Brit. She would hate to acknowledge the Pakistani part... She's more Brit than the Queen herself. Despite living in a ghettoized Lahori household, Alvira has that stiff upper lip attitude towards the riffraff... especially those crass Southalliyas with their lack of polish and their over-friendliness. That job she has as Manager at the House of Fraser's is a godsend. She can hobnob with the hip Bond Streeters any time she likes... Yea, that's what she calls 'class'...
