In an alternate present-day version of Oakland, Cassius Green (Lakeith Stanfield) is struggling to make a living. He gets a job as a telemarketer, but it's not until a fellow black employee (Danny Glover) advises him to use his "white" voice, that Cassius becomes successful. He gets promoted to being a "power caller," which puts him on the upper floor, where he's provided all kinds of perks.

However, he soon discovers that what he is being asked to do is morally wrong. His girlfriend Detroit (Tessa Thompson) objects, even when CEO Steve Lift (Armie Hammer) offers him $100,000,000.
