One day, Jayakrishnan is persuaded to write a letter on behalf of his friend Thangal, a pimp, to a girl named Clara. The letter is intended to fool Clara's father, and thereby introduce Clara to the sex industry under Thangal's supervision. As Jayakrishnan writes the letter, it begins to rain. It turns out that Clara is a poor girl who belongs to the coastal fishing community. She has been mistreated by her stepmother, and is trying to escape from her home. She agrees to become a sex worker and meets Jayakrishnan in Thangal's supervision. Their meeting is graced by the rain.
