Explorer: The Deepest Cave

NGC | 10:00 pm

The latest installment in National Geographic's long-running "Explorer" series, this new one-hour special follows cave explorer Bill Stone and his team to Cheve Cave in Mexico, where they try to set a record by venturing into the bottom of what is thought to be the deepest cave in the world. That challenge involves navigating through more than 12 miles of unexplored tight, twisting passages, often in complete darkness. It's a treacherous course where a single mistake could prove fatal, but Stone has recruited a team of 69 elite cavers.
