Nightshade (2022) on Netflix

Homicide Detective Ben Hays (Lou Ferrigno Jr.) has tried everything to cure his insomnia, but nothing works. To make matters worse, Ben and his partner, Detective Beckett (B.J. Britt), are hitting dead ends while investigating the murder of Randy Bell (Jason Patric). Ben reluctantly agrees to see psychiatrist Dr. Collins (Dina Meyer), who convinces him to try hypnotherapy. But as Ben's sessions continue, so do the murders, and he begins sleepwalking and having haunting nightmares that reveal disturbing parallels to the crimes. Ben struggles to explain himself to his wife, Lucy (Kenzie Dalton), and Beckett, who knows something is wrong with his troubled partner. Sleep-deprived and desperate for answers, Ben must race against the clock to discover the cause of his afflictions, the identity of the killer, and above all, his shocking connection to the victims. —Primitive Mind ProductionsPlot summaryAdd synopsisGenresMysteryThrillerParents guideAdd content advisory
