Henry Myers (Drew Walters) is living a hard life, surviving on the frontier any way he can – even if it means robbing a bank. After his latest heist backfires and his partners (Bea Smith and Rio Alexander) betray him and leave him for dead, Henry's life takes a surprising turn when he finds kindness and compassion from a widow (Erin Bethea) and her children (Jaden Roberts and Ezra Proch).

Thomas and his fellow Gladers face their greatest challenge yet: searching for clues about the mysterious and powerful organization known as WCKD. Their journey takes them to the Scorch, a desolate landscape filled with unimaginable obstacles. Teaming up with resistance fighters, the Gladers take on WCKD’s vastly superior forces and uncover its shocking plans for them all.
