As Above, So Below(2014)

In her attempt to locate the Philosopher Stone underneath the Paris catacombs, Scarlett Marlowe (Perdita Weeks) and her group inadvertently enter a circle of hell that torments them with past incidents that have left them guilt ridden. Papillion, Souxie, and Benjy are killed in the process of attempting to escape the catacombs.

Scarlett figures out that if they confront what haunts them and forgive themselves for the guilt they feel, they can escape the catacombs (and by extension the circle of hell they are apparently trapped in). In doing so, Scarlet, Zed, and George are able to find an exit out of catacombs and back onto the streets of Paris, shaken but alive.
