From Netflix:

A police officer and a doctor face an emotionally charged
mystery when seven local residents inexplicably return
from the dead in peak physical form.

From IMDB:

Six people return from the dead with no memory and attempt to unveil what brought them to the grave in the first place.

From Netflix you can patiently (if that is possible in this sad case) stream 3 seasons of unreality. Each season contains 6 wonder-filled episodes of about 54 minutes length.

Succinctly put, these 18 episodes present almost acceptable nonsense for the truly bored.   Each of the “arisen” was murdered in his or her former life and have been given a chance to discover the murderer and to right past wrongs.  At least at first my attention was fixated on amending past injustice. In addition, there are actually some small patches of good acting and character interaction. Unfortunately there was an equal amount of really bad, maudlin (i.e. weeping) acting. As time wore on, good guys became bad guys and sometime became good guys again. Moreover when the plot devolved into the hero-villains trying to save the universe from ending,  I almost threw in the towel. For better or worse I persisted to the end. Now I have to find another trash series.

Waste no time on this clunker.
