A team of researchers ventures deep into a remote cave system to investigate the long-forgotten disappearance of a family member. It soon becomes apparent that they cannot count on any help from the local population. Their first encounter quickly escalates into verbal hostilities. However, one person does seem interested in their story and invites them to discuss it quietly. His intentions may be dubious, but he can help them find the right cave to begin their search. However, once underground, they are soon hunted by a terrifying supernatural presence lurking in the darkness. As paranoia and fear take over, survival becomes a desperate battle against an invisible force that knows the tunnels much better than they do. BONE KEEPER is a claustrophobic British horror film by director Howard J. Ford, starring John Rhys-Davies, that is reminiscent of The Descent from twenty years ago. Full of suspense and featuring very successful creatures, this film can already crown itself one of the better productions of 2026.
