Adam Zantz is still driving for Lyft, struggling to make ends meet, when his beloved former piano teacher makes a deathbed request: He wants Zantz to prove his son’s innocence in a decades-earlier murder case. There doesn’t seem to be much hope of solving such a cold case --- until Zantz stumbles onto a test pressing of a never-released vinyl LP. The recording is of a high school garage band lost to the tides of the Paisley Underground, the acid-fueled early ’80s music scene that spawned the Bangles and the Three O'Clock. Down the psychedelic rabbit hole Adam falls, tracing the band's journey from the middle-class garage to the precipice of fame --- a twisted tale marked by crooked DJs, elder-scammers, wellness hucksters, a teen cult, and the woman who held the key to the band’s triumph and ruin.

A struggling songwriter and Lyft driver, Adam Zantz’s life changes when he accepts a ride request in Malibu and 1970s music icon Annie Linden enters his vehicle. Bonding during that initial ride, the two quickly go off app. Over the next three years, Adam becomes her exclusive driver, and Annie listens to his music. Then Annie disappears, and her body washes up under a pier. Left with a final cryptic text --- “come to my arms” --- a grieving Adam plays amateur detective, only to be charged as accomplice-after-the-fact. Desperate to clear his name and discover who killed the one person who believed in his music when no one else in his life did, Adam digs deep into Annie’s past and comes to question how well he (or anyone else) knew her --- if at all.
