First seen wearing a headscarf as she explores an off-limits cavern in Iran, gorgeous tomb raider Scarlett (Perdita Weeks) claims to be a black belt in Capoeira while holding a doctorate from University College London. Cue up lots of stinging sound effects, eerie chanting, rats, a freaky dude named "the Mole" (Cosme Castro) who pops up now and then, and a slew of lame paranormal gags whereby each character is forced to face their own inner demons. At best, the filmmakers capitalize on their Paris locations, staging a few scenes in the actual catacombs (still a popular tourist attraction), others in a trendy nightclub and empty Right Bank cathedral.
