Travel vloggers Teddy and Claire run a channel called "SUPERHOST," where they share their experiences in and around vacation homes, and until recently, had become successful doing it. With a dwindling subscriber count, they find the perfect opportunity to create content that people want to see when they meet Rebecca, the host of their most recent trip. Slowly they start to realize that something isn't right with Rebecca, and as they investigate it further, they unlock a horrifying truth. She doesn't just want a great review, she wants something far worse.
