postmaster. Balan struggles to balance his professional life amidst his multiple interests, which include
amateur theater and a penchant for helping others, including strangers. Nevertheless, he leads a cheerful life, with the support of his loving family, and is a respected figure locally, earning the name Balettan (Balan, the elder brother). However, his
good samaritanism, amateur interests and carelessness leads to circumstances that leave him deep in debt and he even gets arrested for cheating on false charges. His father bails him out of the problems with his
pension savings, and expects Balan to become more responsible towards his family. One day, an unexpected

After his father's death, Balan tries to realign his life between the two families and struggles with it. His family starts suspecting him of having an affair, as he is spotted with his half-sister. Amid the chaos, a stranger named Bhadran comes into Balan's life with sinister intentions, and blackmails him, with an eye on his half-sister. The rest of the story tells how Balan manages to solve his problems, including Bhadran's threats and getting his second family accepted in the society. == Cast ==
