The night before Easter unfolds with a ruthless mugging. Remington, Timothy Muskatell, breaks into a convenience store with a shotgun, leaving the clerk—shot in the mouth—injured and terrified. He soon insinuates himself into the life of widow Mindy Peters [Charlotte Marie], a nurse who shares a home with her cerebral palsy–afflicted son Nicholas [Ricardo Gray]. Remington needles Mindy’s routine and, more troublingly, torments Nicholas when Mindy isn’t around. Nicholas also befriends a disfigured homeless man who gives him a rabbit, claiming it is an Easter Bunny, and the boy keeps the gift a secret, hoping to protect it from the threats he senses in his new world. Yet Remington discovers the rabbit’s existence and threatens to kill it if Nicholas ever tells Mindy about him, tightening his grip on both mother and child.
On Easter, Mindy must work a double shift, so she leaves Nicholas with Remington after the latter ejects some unscrupulous home renovators. No sooner is she gone than Remington assaults Nicholas and summons a physically disabled and pedophilic acquaintance named Ray [David Z. Stamp], whom he “rents” Nicholas to in exchange for money and drugs. Meanwhile, Remington heads out to procure prostitutes, leaving Ray to track down Nicholas. As Ray searches, a killer wearing Remington’s discarded Easter Bunny mask murders Ray with a knife and a drill, and then disposes of the body. The renovators return to collect their tools and ransack the house, while the masked killer—still unseen—disembowels one man with a circular saw and wounds another with a hammer, as a second threat, the vagrant, closes in.
Remington eventually returns with Candy and Brooke, two prostitutes [Kele Ward], [Amy Szychowski], and the night escalates into a brutal confrontation. The injured handyman is killed with a flashlight, Candy is impaled through the mouth with a broomstick handle, and Brooke is stabbed with a shard of glass. Remington himself is fatally wounded, and the killer is revealed: Mindy. She taunts Remington as he dies, confessing her long-held fury with his treatment of Nicholas: “I hid, and watched, and I saw how you treated Nicholas. I heard every venomous word that spewed through your deceitful mouth. Until I ended it. Just like his father.” A flashback then reveals Mindy’s past: a decade earlier she set her abusive husband Donald on fire because he treated Nicholas as a burden, a moment that casts her actions in a dark, defensive light.
The homeless man who entered earlier returns and is revealed to be Donald, the same figure Mindy once burned out of her life. He asks for forgiveness and acceptance back into the family, presenting Mindy and Nicholas with the severed head of a renovator he had murdered to help Mindy. The trio embraces in a fragile, morally complex moment as Donald looks to the future, and the film closes with his chilling invitation: “Now, what do you say we clean up these dead bodies, and start a family, huh?”
