Veteran documentary filmmaker and hipster Lech Kowalski creates this film about his friend and hard-partying rock god Johnny Thunders, member of legendary proto-punk band the New York Dolls. Through archive footage and interviews with such musicians as Dee Dee Ramone and Sylvain Sylvain, the film details his stint with the Dolls, the formation of his other band, the Heartbreakers; his rise to fame, particularly in Japan; his descent into heroin addiction, and the mysterious circumstances of his death.

January 1978. After their success in England, the punk rock band Sex Pistols venture out on their tour of the southern United States. Temperamental bassist Sid Vicious is forced by his band mates to travel without his troubled girlfriend, Nancy Spungen, who will meet him in New York. When the band breaks up and Sid begins his solo career in a hostile city, the turbulent couple definitely falls into the depths of drug addiction.

Filmed in documentary-style, the film follows the character of Gringo, a young man looking for fortune in New York, only to fall into heroin addiction.
