Horror in Church. Underground/Tunnels narrowing

Movie ends with walls closing in narrowing. I think the tunnels or underground are accessed via a church? It’s set in Britain or Ireland, sure it’s within the last 20 years, probably last 10.

At the end I think 1 or 2 of the cast go into the underground/tunnels I believe the priest/vicar possibly becomes evil might be chasing them, they get deeper and deeper into the hole/tunnel and they get more and more panicked then the walls start to Physically narrow to the point of no return.
