On June 29, 1981, in the heart of Los Angeles, we are drawn into the tumultuous life of John Holmes, an infamous adult film actor, portrayed by Val Kilmer. The narrative introduces us to his young girlfriend, Dawn Schiller, played by Kate Bosworth, who is navigating the turbulent waters of adolescence and troubled relationships. After a volatile breakup with Holmes, Dawn finds herself wandering the streets until she is picked up by a woman named Sally, a self-proclaimed holy roller, played by Carrie Fisher. Eventually, Dawn reaches out to Holmes, and in a moment that melds illicit romance with addiction, they are soon enveloped in a haze of drugs, intimacy, and fleeing from the repercussions of their choices.

The duo embarks on a chaotic ‘drug-run’ to Wonderland Avenue, nestled in the dense foliage of Laurel Canyon. This journey leads them to a motel where they indulge in freebasing and snorting cocaine, further entangling themselves in a world shadowed by addiction and crime. The following morning, however, marks the beginning of a harrowing ordeal for Dawn, as she awakens alone in the motel room with their pet dog, left behind when Holmes departs to check his messages in Santa Monica. Promising to return shortly, he vanishes for several hours, leaving her to confront chilling visions and solitude.

When the sun sets on June 30, Dawn is jolted awake by a news report detailing the grim discovery of four brutal murders at the row house on Wonderland Avenue—the very place she had visited with Holmes just a day before. When Holmes returns, he appears disheveled and evasive, opting for silence and rest instead of sharing the disturbing truths of his whereabouts.

As the narrative unfurls, we encounter detectives Nico and Cruz, played by Ted Levine and Franky G respectively, who are deeply engrossed in unraveling the labyrinth of violence surrounding the Wonderland murders. Their investigation introduces us to David Lind (Dylan McDermott), whose night at a local bar turns tragic when he learns of his girlfriend’s involvement in the horrific events at Wonderland. His narrative, pieced together through flashbacks, sheds light on the notorious Wonderland Gang, led by the conflicted Ron Launius, portrayed by Josh Lucas, amidst a swirling array of characters caught in the throes of addiction and crime.

As chaos unfolds, we see Holmes infiltrate the Wonderland lifestyle, leading him to serve the gang at the risk of his own safety. Torn between loyalty and survival, his escalating drug dependency propels him into the darker realms of organized crime. A pivotal moment arrives when Holmes, seeking to regain favor with the Wonderland Gang, suggests robbing their connection, nightclub owner Eddie Nash (Eric Bogosian).

One fateful robbery culminates in bloodshed and betrayal; Holmes circles back to a night of horror when his association with Nash brings forth dire consequences. Nash’s retaliation is swift, leading to a brutal confrontation on July 1. With a gun to his head, Holmes is coerced into witnessing a massacre that forever alters the lives of everyone involved.

Through intertwined destinies, the story meticulously unravels a tapestry of conflicting testimonies, entangled lives, and the haunting choices made amidst soaring drug use. Grand illusions of glamour quickly decay into stark realities of blood and betrayal, as both law enforcement and the characters grapple with the shadows of their past.

In an epilogue cloaked in tragedy, we glimpse the aftermath: David Lind is ultimately consumed by his addiction; Dawn Schiller escapes the torment of her relationship with Holmes but engages in a heartbreaking rendition of turning him into the authorities; while Holmes himself, acquitted of murder yet forever marked by his past, spirals into a tragic end, succumbing to AIDS in 1988. The course of lives being irrevocably altered serves as a stark reminder of the heavy toll that addiction, violence, and choices can extract, enveloped in a haunting melody as Holmes and Dawn drive into oblivion, leaving behind the scars of their past lives.
