Triyatri(1990)

Bright students Ravi, Adi and Surya are angry when they find out that their high school marks are just below the cutoff mark to get an entrance to the college of their choice. Out of frustration, Ravi twangs his guitar during his grandfather's classical music lesson. The old man, instead of getting angry at this behavior, challenges the boys first to a musical contest and then to a cycle tour to Kanyakumari. These challenges test the young kid's minds, characters and endurance.
