Sixties folk singer Dane Donovan vanished from a desolate highway rest area in 1979. Forty years later, he's found hitchhiking in the California desert on a cold winter's night. He hasn't aged a day, but the roadmap of scars he wears tells a chilling tale.

Veteran detective Walter Muse took over Dane's missing persons case twenty years ago, but his haunting connection to Dane Donovan goes back to a peculiar run-in as a child with The Troubadour and his Talking Board at a traveling carnival. He receives a late-night call with Dane's whereabouts and races to Laurel Canyon to see for himself whether Dane is real — or a ghost meant to taunt Walter and his somewhat precarious hold on his sanity. Walter's carefully honed detective instincts are thrown out the window, however, when his obsession with the case develops into an undeniable attraction to the mysterious singer.

Dane is on a mission to stop a new killer hell-bent on picking up where Dane's kidnapper left off, and Walter is determined to protect him, no matter the personal and psychological cost. They'll have to rely on new friends and trusted colleagues as well as the power of a mystical spirit board to stop the killing, and have a chance at a real future together.
