‘Reborn,’ ‘The Court’ and ‘Rough Justice’ From ‘Walter Presents’ Library Streaming in May From PBS

PBS Distribution will begin streaming three international crime dramas from the “Walter Presents” library on the PBS Masterpiece Prime Video Channel in May.

The channel is available to Prime members for $5.99 a month after a seven-day free trial.

Streaming beginning May 10 is “Reborn,” a French crime-thriller taking witness-protection to a whole new level. Felon Alexis Marceau gives up his criminal friends in exchange for immunity. With his new identity, he also has reconstructive surgery to make him unidentifiable. Six years later, he is known as Matthias Leblanc. He is working in Turin, Italy, as a construction worker when judge Delphine Baron offers to revoke his house arrest, in exchange for three months of service. This means working undercover at his old job where he and his partner ran a small shipping business controlling the traffic of illicit goods. Matthias is hesitant but accepts — no one knows he’s alive or will recognize his new face. But he knows the people, place and methods better than anyone. Once undercover and back in Dunkirk, Alexis struggles to keep away from his ex-wife and son. And to make matters worse, his affection for his old life returns — the camaraderie, the easy money and the adrenaline.

Streaming beginning May 24 is the second season of “The Court.” The Icelandic legal drama follows the professional and personal lives of three Reykjavik lawyers — Logi, Brynhildur and Hordur. Logi is one of the country’s most brilliant legal minds and the most troubled. He’s determined to uncover the truth about what really happened one night in his youth, an incident that left a man dead and Logi in prison for manslaughter. However, his internal demons threaten to send him spiraling into alcoholism. Standing between Logi and self-destruction are his two lawyer colleagues — Brynhildur and Hordur — whose own private lives are far from simple.

Streaming beginning May 31 is the Belgian crime drama “Rough Justice.” Set in Antwerp, Belgium, the series, based on the novels by Toni Coppers, follows superintendent Liese Meerhout as she leads her close-knit team in the homicide division to the bottom of the city’s darkest crimes. Always seeking to protect the vulnerable and maintain justice, she is not afraid to push the boundaries to get to the bottom of even the most complex cases — usually using unorthodox methods. But when haunting emails from an anonymous sender start appearing in her inbox, a case she thought she had long put behind her resurfaces, and the usually steely and implacable superintendent becomes unnerved.
