Darkness Falls (2020)

In DARKNESS FALLS, two men (Richard Harmon and Gary Cole) force a woman to take sleeping pills, place her in a bathtub, and slit her wrists. Her husband, police detective Jeff Anderson (Shawn Ashmore), comes home and finds her. When their son, Frankie (Judah Mackey), talks about a "bad man" who came into his room that night, Jeff becomes convinced that his wife's death wasn't a suicide. He moves himself and Frankie in with his mother (Lin Shaye) and feverishly starts the impossible task of finding the killers, whose execution was perfect and left no clues. Meanwhile, Jeff's former police partner (Daniella Alonso), who has received a promotion, worries about his erratic behavior, and his job could be in jeopardy. Can Jeff find that elusive clue and catch the murderers?
