In the sultry heat of a Tamil summer, Sudha, a married woman with a secret yearning, finds herself alone with her brother-in-law. As they chat, the air thick with tension, Sudha's eyes betray her, lingering on his toned body.

Sudha, her inhibitions melting away, leans in, 'Maybe you should join me.'
