Nothing Personal (2010)

A woman dumps all of her belongings on the sidewalk like she's hosting a 100% off sale and takes off on foot. She hitchhikes and camps out until she finds a lonely house with a lonely man. Although the woman demands privacy and seems to prefer solitude, the two people gradually form a functioning household.

We never find out backstory -- it’s like opening a novel in chapter 4 and just getting on with it. But, somehow, that was alright.
