After getting exiled by Lord Rama, Devi Sita gives birth to two sons Lava and Kusa. Under Sage Valmiki's guidance, the boys set out to preach the Ramayana in Ayodhya but a shocking truth awaits them there.

The show is a follow-up to Sagar's highly successful Ramayan (1987), featuring mostly the same cast and production crew. Lav Kush covers the last book of the Hindu epic Ramayan- the Uttara Kand, following Rama's coronation, especially focusing on his sons Kush and Lav.—AB THE BOSS
