Low-budget but captivating, till you get to the end and have to run it fast-backwards in your mind, realising that the premise as it now stands is as improbable as Hell. I'm not going to spoil the film for you, as we are in Hallowe'en season and it can be watched for free on Fear.net or cable tv, but I will tell you that it is set in the Catacombs of Paris.
The leading actress was good. The "French" antagonist had such poor French that we pegged him as Eastern European. Watching the credits, we learned that this was a Romanian production
with negligible French participation. I recommend this film because it is both fascinating and scary.
