This is a biographical film about Sid Vicious (Gary Oldman), a punk rocker from England, and his girlfriend, Nancy Spungen (Chloe Webb), an American. Sid plays with a band called The Sex Pistols and becomes a drug abuser along with Nancy, who is already addicted to heroin. They are completely devoted to each other and do not want to be apart. The band disintegrates after a while because of this. Sid and Nancy’s lives take a turn for the worse after that. They go to live in the Chelsea Hotel in New York, without any money or hope for the future.
