A missing child causes four families to help each other for answers. What they could not imagine is that this mystery would be connected to innumerable other secrets of the small town.
Also seconding Dark. Too much much bleak violence and pseudo-profundity for my taste but still superb IMO.
Seconding Dark. It's not an episode, but an entire TV show, though. But the time travel is great.
Dark is very good.
