Something To Hide (1972) British crime/drama with Peter Finch, Shelley Winters & Linda Hayden.

A man suffering marital problems, picks up a pregnant hitch-hiker, and tries to help her out by letting her stay at his cottage for a few days whilst his wife is away.
His life is turned upside down from the stresses of work, his wife and the hitch-hiker, leading to a foreboding, and unexpected, conclusion.
This print is slightly longer, and sharper looking, than other versions on YouTube. I also toned down the colour saturation, and changed the hue to be slightly bluer and more natural, while I feel the other copies have a more greenish hue/tint to them.
