After wowing audiences in the ‘Dirty Picture’ Vidya Balan returns this month in another challenging role.

Kahaani tells the story of Vidya Bagchi (Vidya) who arrives in Kolkata from London to find her missing husband.

Seven months pregnant and alone in a festive city, she begins a relentless search for her husband.

With nothing to rely on except fragments from her memories about him, all clues seem to reach a dead end when everyone tries to convince. Vidya that her husband does not exist.

She slowly realises that nothing is what it seems. In a city soaked in lies, Vidya is determined to unravel the truth about her husband – for herself and her unborn child – even at the cost of her own life.

Kahaani is the latest movie by maverick filmmaker Sujoy Ghosh, who blends art with intrigue on screen.

Set against a menacing backdrop of Kolkata by-lanes and alleyways, Kahaani presents Balan in her fifth female-centric role to date.

The movie is complimented by a haunting soundtrack, courtesy of Hindi cinema’s gifted composing duo, Vishal-Shekhar.

The musical score has already received a level of praise from film legend Amitabh Bachchan Bachchan wrote: "May I just say that singing Rabindra Sangeet for the first time was the greatest revelation.

“The beauty of the language, the lyricism of the tune and its dhun (music) are outstanding.

"This particular, world famous number Ekla Cholo, expounding to all that if no one came to you on your calling, walk alone! And what a fabulous song has been incorporated by Vishal-Shekhar. Truly awesome and worthy of all award."

Kahaani releases in UK through B4U Pictures on 9 March.
