Prabhu (Pavish Narayan) is on the verge of accepting the proposal of Preethi (Priya Prakash Varrier), yet he hasn't moved on from his ex, Neela (Anikha Surendran), who is hours away from marrying someone else. At her wedding, as alcohol flows freely, Prabhu's best friend Rajesh makes a confession of his own: he has feelings for Sriya, who has spent the last seven years in a committed relationship with another of their closest friends. If the characters of Jabilamma... seem engaged like a tangled relational equation with no obvious solution, then that's entirely the point.
