"Ozzy: The Prince of Darkness" is a chaotic, darkly comedic, and tragic ride through the 1980s. The film begins in 1979, with Ozzy Osbourne fired from Black Sabbath, locked in a hotel room in Los Angeles, surrounded by pizza boxes and drugs, convinced his life is over. Enter Sharon Arden, the daughter of his terrifying manager, who decides to drag him out of the darkness and turn him into a solo star.
The film tracks the manic highs of the Blizzard of Ozz era, the legendary biting-the-head-off-a-bat incident, and the drunken debauchery that made him a public menace. However, the emotional core is the "father-son" musical bond he forms with the young guitar prodigy Randy Rhoads, whose classical influence revitalizes Ozzy’s music. The climax is the devastating 1982 plane crash that kills Randy, sending Ozzy into a spiral that only Sharon’s ruthless love can save him from. It’s a story about a man who tries to drown his demons, only to find out they can swim.
