Eventually, seeing his fellow co-workers have their lives destroyed, he decided to leave the place and go to Chennai and work in cinema.

He then went on to work as an assistant director in the Tamil feature film Manjapai (2013), directed by Raghavan and produced by Sarkunam.

Vinothraj, along with his team, shot the film in around 37 days in the peak hours of sunlight during the noon as he wanted to capture the heat of the landscape.

[13] PS Vinothraj's recent film The Adamant Girl (Kottukkaali), written and directed by him, is produced by Sivakarthikeyan Productions LLP.

The story centers around Meena, a young woman trapped in a stifling family dynamic, forced into an arranged marriage with Pandi while being in love with someone from a lower caste.

The film is noted for its raw, unsentimental portrayal of societal structures, echoing the director's style from his debut feature Pebbles.
