The core premise remains deceptively simple: A family welcomes a guest (Atithi) into their home. However, in this universe, Atithi Devo Bhava (The guest is God) becomes a curse rather than a blessing.
In , the "guest" is not a stranger but a childhood friend named Joy (played with chilling restraint by a newcomer actor, a hallmark of KooKu’s casting).
