Bassist-turned-junkie Jonny Wells is addicted to his past, and the only way to get there is through the music.   The bassist of a breakout '90s punk band, Jonny falls apart when his band mate and best friend Kirk commits suicide. Twenty years later he struggles with heroin addiction, lost in the songs they created and desperate to relive the past, when he discovers that he can--literally. With the aid of a mysterious guitar, Jonny begins to make trips back in time, searching for the roots of Kirk's unraveling. At Nar-Anon meetings and in conversations with his sponsor Emily, he starts to cope with the events that led to Kirk's death. But by the time Jonny realizes that his visits can't change the present, he might be too addicted to stop.
