Janis Joplin 
Her Final Hours

Janis Joplin is the undisputed queen of rock and roll. It's a fact that there had been no female superstar of rock before Janis came along. Her rule of thumb was if it feels good do it.
Janis also hides her self-destructive, darker side. She was a very troubled girl and a genius and at the same time she was looking for some kind of relief to not have to be Janis.
A blast of nearly pure heroin will end her short, dazzling career. This is the analysis on the life and death of Janis Joplin, the undisputed queen of rock and roll.
This riveting documentary (which plays out almost like a detective story) painstakingly unravels the still-disputed events which brought down the queen of rock 'n' roll.
You'll revisit Janis's early life and meteoric rise to fame, then discover how her out-of-control drug addiction and a cut of nearly pure heroin ended it all.
