Pushpa and her uncle Appasami try to abort the baby, but Radha safely delivers a boy. While Radha is in a delirious state, Pushpa and Appasami hand over the baby to a servant, Gopal and order him to kill it. But Gopal takes it to the next village and dumps the baby in a garbage bin. Kaathaan comes to clear the bin and finds the baby. He and his wife Pechi decide to bring up the baby, name him Marudhan and move on to the Zamindar's village in order to escape from neighbours' prying eyes.
