Pretty sure it was on Netflix around 4 years ago. Some teens left their town for some kind of trip and when they returned there was nobody left in the town, like they’d been forcibly taken for some reason and all of their belongings were left behind. I can’t remember much else but I definitely liked it and I asked the friend I was watching with if there was going to be a sequel because it was left open, they said a sequel was already being made. (I no longer speak to this person otherwise I would just ask them)
