The Woods (2020)

The Harlan Coben adaptation with the most ache in it. A Warsaw prosecutor is asked to identify a murder victim, and the case leads straight back to the August 1994 summer camp where he was a chaperone and where his sister was one of two people who disappeared. The story moves between that summer and 2019, so you see the teenagers before the night that defined them and the adults still carrying it. This Polish series is six episodes, tighter than most Coben shows, and it is at its best on what 25 years of not knowing does to a family that never stopped hoping. Watch it with subtitles if you can.
