Continue to check back with us as we will be adding more information as it becomes available. MGM+ has been quietly stringing together a strong run of original, star-and-creator-driven programming on streaming over the past two years. Before that 70s-set thriller hits the screen in September, though, MGM+ is about to take viewers through the best and worst of times once again. Their tale begins after Lucy receives the letter and, after finding that the messenger Darnay has been arrested for treason, relays her story to Carton. He agrees to help over drinks, but he warns her it won't be easy, and even being associated with a suspected traitor will put her at risk.
