Set decades after the events of the original The Green Mile, the sequel introduces Marcus Stone (Idris Elba), a mysterious death row inmate with abilities eerily similar to John Coffey’s. Marcus is convicted of a violent crime but insists he’s guilty of his past sins. However, his arrival at Edgecomb Penitentiary sparks a series of unexplainable events, including miraculous healings and prophetic visions.

Evelyn Marks (Jodie Comer), a compassionate death row officer, becomes intrigued by Marcus’s claims and powers. As she delves deeper into his past, she discovers he shares a spiritual connection to Coffey, with a purpose tied to preventing a devastating future. Marcus foresees a catastrophic prison riot that could result in hundreds of deaths, including hers.

In the climactic act, Marcus uses his powers one final time to prevent the riot, sacrificing himself to save both guards and inmates. His death brings peace to those around him, leaving Evelyn to grapple with the meaning of justice, miracles, and faith.

The film ends with Evelyn visiting Paul Edgecomb (Tom Hanks) in a nursing home, seeking solace and answers about Marcus’s connection to Coffey. Paul assures her, “The light always finds a way to shine through the darkness.”
