Nathan Fielder returns to television to explore the lengths one person will go to reduce the uncertainties of everyday life. Fielder stars as the director of rehearsals, which are elaborately staged scenarios re-creating parts of ordinary people's lives that are meant to help them prepare for a big moment in their lives. A construction crew, a legion of actors and seemingly unlimited resources all come together to allow ordinary people to rehearse for these moments by giving them the opportunity to play them out in carefully crafted simulations of Fielder's own design.
