Story…Ramachandran aka Ram (Vijay Sethupathi) is a travel photographer. He visits his high school and is overcome by memories. So, a reunion is arranged through their school WhatsApp group. At the reunion, his friends Murali (Bagavathi Perumal), Subhashini (Devadarshini) and Sathish (Aadukalam Murugadoss) catch up with him. Murali hesitantly mentions that Jaanu (Ram’s childhood sweetheart) is coming from Singapore.

In 1996, Ram and Jaanu have been friends and classmates in 10th grade. Jaanu is a talented singer. Ram develops a love for Jaanu and she reciprocates. Once their board exams are over, they have a moment with each other where Jaanu asks him not to forget her until they meet again after the holidays.
