Sapta Sagaradaache Ello (Side B) begins with Manu (Rakshit Shetty) emerging from prison after a decade. However, as the story progresses, one gets to see he is still mentally imprisoned in his past. While the film's prequel, Sapta Sagaradaache Ello (Side A) had shown Manu as inseparable from his girlfriend Priya (Rukmini Vasanth), how a misguided decision lead to their separation and her attempts to cope with the circumstances, 'Side B' showcases Manu's perspective.

The sequel is about Manu's obsessive pursuit of Priya, though she is now married with a child. Even his affection for Surabhi (Chaithra J Achar), a sex worker, stems from his perception that she resembles Priya though she is nothing like her. The spectrum of emotions he goes through is eloquently put together in the 148-minute movie.
