In Phantom Ranch, estranged brothers Ben and Todd Brady set out to honor their father’s dying wish by hiking the treacherous trails of the Grand Canyon. The trip, intended as a final tribute, turns into a nightmare when they stumble upon Condor Mark, a notorious serial killer hiding within the canyon's vast expanse.

Ben, a successful entrepreneur from Atlanta, is an outdoor enthusiast who reluctantly agrees to reconcile with Todd, his temperamental brother from Oregon, for the sake of their late father’s memory. Despite their personal differences and past conflicts, they head into the Grand Canyon, joined by Ben's friends, who aim to mediate the tension.

As the group ventures deeper into the canyon, they encounter a series of unexpected dangers, heightening the stakes of their expedition. The situation escalates when Ben befriends a mysterious loner at Phantom Ranch. This new acquaintance, however, is not who he seems to be, and his true identity threatens everyone's safety.

Forced to confront their fears and unresolved grievances, Ben and Todd must overcome their personal animosities and work together to escape the canyon alive. In their desperate bid for survival, they not only have to evade a cunning predator but also reconcile their fractured relationship.

Phantom Ranch combines the suspense of a thriller with the emotional depth of a drama, exploring themes of redemption, brotherhood, and survival against the backdrop of one of nature's most formidable landscapes. This gripping narrative promises to keep audiences on the edge of their seats while touching on the profound bonds that define family.

It is based on a true story of who we believe to be the infamous serial killer, Robert Durst.
