Sumpuously shot in and around a French port and a delightfully delapidated chateau, a young French girl (aren't they always so delicate and pretty) finds a job with a strangely obscure scientist who "preserves" things. "People find their way here" is obscure and we see a succession of customers who come to have anything from some dead mushrooms to a facial scar preserved. Thus they find release from whatever torments them.
Esoteric, ambiguous and happily sustaining itself, the film's ending is not unexpected, but it does resolve in a way. What that way means is up to your own interpretation.
If you like good cinema rather than action and explosions, then this could be for you.
