After the 150th marriage rejection, he buys a flat in a beautiful apartment. As soon as he moves to his new flat, Anjanam gets the nod from the former bride Meghala's (Priya Bhavani Shankar) side. Though the new house turns out to be lucky for Anjanam, he cannot sleep peacefully because of a naughty rat, which turns his house and life upside down.
