From Amazon Prime:

Irene and Franklin York, a retired couple, have a secret: a Chamber buried in their backyard that miraculously leads to a strange, deserted planet. When an enigmatic young man arrives, the Yorks’ quiet existence is upended and the mysterious Chamber they thought they knew so well turns out to be much more than they could have ever imagined. Starring Sissy Spacek and JK Simmons.

From Amazon Prime you can stream the 8 episodes of season 1 of this Amazon Original series. Each episode lasts a bit less than one hour.

Never mind the escape portal to another planet. Do not think of this story as science fiction. That other planet is not important to the plot. Central to the plot are two themes: The enduring love between the elderly couple  Irene (Sissy Spacek) and Franklin York (JK Simmons); The efforts of a religious cult to discover all the portals and eliminate, i.e. kill,  all “apostates” from the cult.

Acting, especially the interaction between Irene and Franklin, is worth watching.

Among the actors we find:

• Sissy Spacek was 73 years old during filming. Perhaps you recall her as the telekinetic prom queen in the horror film “Carrie”.
• Although the name J.K. Simmons might not ring a bell, he played, among zillions of roles, the psychiatrist Dr. Emil Skoda in the original “Law and Order”. During filming he was a young 67 years old.
• Adam Bartley plays the bearded troublesome neighbor Byron. Previously I have strongly recommended the long-running series “Longmire” in which Bartley plays the clean-shaven “The Ferg”. During filming he was a mere child of 43 years age.

Rest assured that the startling ending of episode 8 obviously demands another season. Season 1 certainly had me hooked.
