All three of the superpowered characters have been institutionalized where a specialist played by Sarah Paulson attempts to cure them of their psychosis. When Crumb and Price, also known as The Horde and Mr. Glass, unite to reveal their existence to the world regardless of the body count it requires, it’s up to David Dunn, now called The Overseer, to stop them.
