Kalki Koechlin's romantic comedy Happy Ending is in theatres right now, but the actress is set to return to serious subjects.

She has given her nod to a project titled Mantra, which is being developed at the co-production market of NFDC, currently underway at IFFI, Goa. The film will be directed by Nicholas Kharkongor, who had earlier helmed the short film, Fair And Lowly.

Mantra is set in the late 1990s when the Indian economy was liberalised to let in global players. Rajat Kapoor plays an industrialist whose life is affected by the changing markets. And Kalki will be seen playing his daughter.

Confirming the same, Rajat told Mirror, “My character runs a successful business till international players become competitors. Its effect on my family is symbolic of the transition India was going through at that time. Between the late 90s and early 2000s, the face of the country changed completely.“

Rajat and Kalki had earlier collaborated on the play, Hamlet The Clown Prince, helmed by the actor with Kalki playing Ophelia.
