Pradeep (Pradeep Ranganathan) and Nikitha (Ivana), both IT employees, are deeply in love. Pradeep's sister Divya (Raveena) recently got engaged to a dentist (Yogi Babu), and wedding plans are in the works. Pradeep agrees to meet with Nikitha's father to ask for her hand after his sister's wedding is over.

However, Nikitha's father Venu Sastry (Sathyaraj) detects their love and invites Pradeep to their home. Sastry agrees to their marriage if they agree to his condition of exchanging mobile phones for one day. They agree to it half-heartedly and exchange their phones.

Will they check each other's phones? What difficulties would they face as a result of this unusual condition?
