The movie opened to positive reviews with critics stating, "The film has all the makings of a commercial potboiler that should see it sailing smoothly through the box office seas for a while. Way too superior to the generic thrillers being churned out by the dozen, `Masters` is a cool chiller for this summer, that delivers its jolt moments with aplomb.`

She then appeared in movies like Sattam Oru Iruttarai, Backbench Student, and Dalam before making her Bollywood debut in 2014 with the romantic comedy Mumbai Delhi Mumbai opposite Shiv Pandit.
