Billy's Got a Bad Brain (2017)

Student volunteers are disappearing but no one seems to notice. The indifference is the perfect cloak for Dr. Billy Brackett as he dispenses questionable experiments on his college subjects all in an effort to save Becca, his comatose wife. As Billy slowly descends into madness, Professor Arthur Bixby is tasked with evaluating his mental health, but may soon find himself in the middle of a mad scheme.
