Meera (Asin) was a playful girl in Kaavalan who liked to play games. But things soon spin out of her control and she falls in love with Bhoominathan (Vijay) who is also in love with her but just doesn’t know it because to him she is just an unknown entity who talks to him on the phone. It is a pretty little mess and Meera’s friend, Madhu uses it to her advantage and steals her best friend’s man for herself when the opportunity presents itself. Meera does get her man back eventually but she could have saved herself a world of grief if only she had used her head more and her mobile less.
