Butter (1998)

Freddy (Shemar Moore) is a big-shot music industry executive, whose cousin, Blusette (Salli Richardson), is a successful and well-known singer managed by 8-Ball Harris (Ernie Hudson). Blusette soon realizes, however, that 8-Ball is a small-time crook, hoping to use her and her renown to benefit his various schemes. Blusette tells him to take a hike, and she turns up dead a short while later. Freddy then tries to uncover the truth about Blusette, while 8-Ball works to frame him.
