Patty McCormack returns as the evil mother who has been sent to death row since the events of the last film. After a failed escape, she's given an experimental implant to stop her from having her murderous impulses and is sent back out into the world to test it out. Soon, the murders start back up again aimed at anyone who's tried to keep her away from her daughter. Is someone setting her up or is Mommy back to killing again?
Mommy's Day is just as cheap and low budget as the previous film, but that's all part of the charm. It takes a similar approach as Psycho II and gives McCormack's psychotic mother a chance to redeem herself. Some of the murders are creative, especially one with an ice skate and it's not long enough to outstay its welcome.
