After two successful films, Pakistani singer-actor Ali Zafar is back in action with his new romantic movie "London Paris New York" with actress Aditi Rao Hydari that releases Friday.

Directed by debutant Anu Menon, the film puts spotlight on the angst of the 20s, a life altering period when one has to find a career, form an identity and experience the charms of falling in love for the first time.

It is a story about Lalitha (Aditi), a middle-class South Indian girl from Chembur in Mumbai, who is on her way to New York to study politics on a scholarship. She makes a detour to London, where she meets Nikhil (Ali), a rich Punjabi kid from Bandra, who is to study filmmaking in London.

They meet in London and realise they are completely drawn to each other though they know their future lies on two different continents.

The film follows their personal journey as they keep meeting in London, Paris and New York.

The three cities give a dramatic canvas to create different themes.

"London Paris New York" has been shot in three different phases and captures the lead actors' evolving state of mind. The three bridges on three rivers Thames, Seine and Hudson play an important role in the story.

The growing love is reflected through different sets of music like pop romance in London, electronic sufi in Paris and blues-rap in New York.

This is Ali's third Bollywood outing after "Tere Bin Laden" and "Mere Brother Ki Dulhan".
