Veteran actor Radikaa Sarathkumar takes centre stage in Thaai Kizhavi, a comedy drama that blends familial tension with sharp humour. After its theatrical outing, the film is now set to arrive on JioHotstar on April 10, marking its digital debut roughly six weeks post-release.Written and directed by debutant Sivakumar Murugesan, the film revolves around Pavunuthaayi, a strong-willed matriarch whose sudden bedridden state becomes the unlikely catalyst for family reunions. But this is no sentimental gathering.
