More interested in romance than sex, "Formula 17" swoons with youthful innocence. Naive country-boy Tien-Tsai travels to Taipei, where his quest to lose his virginity is impeded by his insistence on finding true love first. The film's Chinese title translates as "17-Year-Old's World" which accurately describes its niche.
