An eerie reflection on dating in the algorithmic age, "Hang the DJ" follows Frank (Joe Cole) and Amy (Georgina Campbell), who both use a device called "Coach" that pairs them with different potential partners for specific lengths of time. When they match, the pair quickly develop feelings for each other — but they're soon paired with other partners. As they try to find each other again, the pair wind up questioning everything about their realities. Like many of the best "Black Mirror" episodes, this one has a thoroughly unexpected, paradigm-shifting ending.
