In an attempt to rekindle their relationship, bicycle messenger Anne and her boyfriend Michael go on a mountain biking holiday, trespassing on a closed trail. There, the beautiful Anne admits to Michael that she slept with (and was possibly raped by) a police officer named Chris. After Anne's confession, Chris (who has been stalking Anne since their night together) slits Michael's throat with his bicycle, and goes after Anne, telling a dying Michael that "she belongs to me".
