Bokeh (2017) on Netflix

Plot summary

Jenai and Riley, two Americans visiting Iceland, tour landmarks and an old church while Riley shoots with his father's Rolleiflex camera instead of a digital one. Jenai's own father is a preacher. Waking in the night, she looks out the window and sees strange flashes in the distance. By morning, breakfast is not served and no staff can be found. The streets are empty, stores have no one in them, and calls to Jenai's family in America go unanswered. Broadcast television carries only test signals, and no website has been updated since the previous day. They take a running car whose owner is nowhere around. Riley treats the situation as something to enjoy, while Jenai keeps calling her family. Power and water still work, and they load supplies from empty stores into two SUVs.
