What will you do if one day you find a girl saying she had a great time with your beloved and wants to spend all her life in his arms? And the only thing you know about her is that you don't know anything about her.
Nimisha travels all the way to Bangalore to celebrate her Valentine's week with Viraj. They did have a great time together but she stumbles upon Shriya to learn Viraj's past. Who is Shriya? A colleague? A friend? Or, more than that?
One & A Half Love Story is a compelling journey of three very different people - Nimisha, Viraj and Shriya.
