The Hidden Face - 2011 - 7/10
AKA - La Cara Oculta

Quicksand thriller from Spain.
Insecure female decides to “test” her boyfriend.
“Does he really love me?”
“Would he miss me if I left?”
She disappears.
Big - big - big mistake.
After a couple of days, he gets drunk at a cafe and goes home with a new bang bunny.

Males, being creatures of limited depth, rarely recall ex-girlfriends once new the new face drains the mojo.
Slow to get going, but a nightmare for asthmatics, the claustrophobic, and the insecure.
