Emulsion (2014) on Netflix

Plot summary

Ronny Maze's wife Isabella goes missing from a car park on the south coast of England. He cannot let her go, and he takes a job at that same car park, standing each night on the spot where she vanished and retracing his own movements for clues. A year on, he lives alone and screens a reel of 16mm film of Isabella every night. Each morning he packs to leave, drives as far as the bridge where he proposed, and turns back. One night a prostitute is attacked in that car park and dragged into a car, and Ronny follows.
