It follows the brief but memorable career of Tammi Terrell, who started out as a backup singer in the James Brown Revue before scoring a few minor pop hits as a solo act. But she struck gold after being paired with hitmaking singer Gaye in early 1967, a teaming that produced such Motown classics as "Ain't No Mountain High Enough," "Your Precious Love" and "Ain't Nothing Like The Real Thing." In October 1967, Terrell collapsed onstage while performing with Gaye, and doctors diagnosed her with a brain tumor. She continued to record with Gaye and scored a few more solo hits before dying in 1970.
