Guest iin London is a film that deals with an odd old couple from rural India who lands up uninvited as guests in a suburban London home of a young couple. What follows is a series of misadventures one after the other turning the young couple's lives upside down.

On another level, the film also captures the socio-cultural differences between the east and the west and in the end with the realization that east or west we all are the same, the emotions are the same and the fact that all we need is love and compassion for each other.
