Allan Alvarez (John Lloyd-Cruz) occasionally takes the Pasig River ferry to go to his newly purchased home. On several of these trips, Allan always sees a girl who writes messages on stones and leaves them behind. He picks these stones up and realizes that messages being written are getting worse and worse as time goes by. One day, when the girl writes Goodbye World, Allan panics and stops the girl from supposedly committing suicide - he soon discovers that this is not the case. He finds out that the girl, Mia Samonte (Bea Alonzo) works as a hotel receptionist in Malaysia. They have exceptional chemistry together, even finding themselves in love after just a week.
