Driven by “an obligation to protect,” Robbie enlists the guidance of local legend Guillermo De Anda. The renowned archaeologist leads them to a dry cave with an ancient altar and other sacred artifacts. On their latest dive, the team scrambles to save fellow diver Jeanna Edgerton, who struggles for air when her equipment unexpectedly malfunctions.
