Still reeling from the end of The Jinx? Not ready to let go of Making a Murder and The People v. O.J. Simpson just yet? The National Geographic Channel is filling the true crime void with Missing Dial, and EW has an exclusive first look at the six-part docuseries.

Missing Dial traces the events surrounding the mysterious disappearance of Cody Dial, 27-year old son of National Geographic explorer Roman Dial. Following in his father’s footsteps, Cody set out on a journey through Corcovado National Park in Costa Rica in 2014… and he hasn’t been seen since.

After searching the Costa Rican rainforest, which is rife with illegal gold-mining and other criminal activity, Roman enlisted the help of two private investigators — Kenneth Fornier (a retired Pararescue jumper) and Carson Ulrich (a former DEA special agent) — and a film crew, hoping the presence of cameras would increase the urgency needed to discover the truth about what happened to Cody. “I was right,” Roman said of his decision to involve the network. “Within a week, we received a significant break in the case.”

Roman previously called for public donations via a GoFundMe campaign, raising $23,610 to help with his search for the truth shortly after Cody’s disappearance in July 2014. For Missing Dial, Roman and his investigators spent eight months combing the jungle for clues, interviewing locals, and scouting for new witnesses.

According to the National Geographic Channel, Missing Dial “pushes further and digs deeper into the mystery, retracing Cody’s last-known whereabouts, using hidden cameras and secret identities to uncover a web of lies, surprising clues and a shocking plot twist that rivals a blockbuster movie.” Though he and his wife, Peggy, spent months contacting the U.S. Embassy regarding the case, Roman said the painstaking search yielded few results. “You don’t know how bad agony can be until your son has gone missing and no one can tell you what’s happened,” Roman said. “It’s a pain that keeps me awake every night, and it’s the same pain that drives me on my search for answers.”
