Mom and Dad (2018) – Full Plot Summary & Ending Explained
Read the complete plot breakdown of Mom and Dad (2018), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

The film begins with a shocking scene where a mother sets her car on railroad tracks, leaving her child inside as the train approaches, accompanied by soothing music. This disturbing act sets the tone for the chaotic events to unfold. We then shift to the Ryan family, a seemingly typical family of four struggling with their own interpersonal issues. The father, Brent (played by Nicolas Cage), disapproves of his teenage daughter Carly’s (Anne Winters) new boyfriend and is caught in tension with both her and his wife, Kendall (Selma Blair). Carly feels her mother is out of touch, while she bickers with her much younger brother, Josh, who annoys her. Plans with her boyfriend, Damon, must be canceled due to dinner with her visiting grandparents, which only adds fuel to the already tense family dynamic.

As Carly is at school, a mysterious static begins to disrupt televisions and radios, coinciding with a horrifying event: the family’s housekeeper brutally murders her daughter with a meat tenderizer in front of a terrified Josh. Moments later, chaos thrives as a mob of parents rush to Carly’s school, intent on harming their children. With great urgency, Carly escapes alongside her best friend Riley, but their refuge is short-lived when Riley’s mom turns on her, leading to a tragic strangulation. Frightened and desperate, Carly runs home, only to encounter Damon, who reveals he has just defended himself against his father in a deadly incident.

Damon explains that the deranged parents seem focused only on harming their own children, leading him to help Carly find safety for Josh. In a parallel storyline, Kendall visits the hospital for her sister Jenna’s (Samantha Lemole) delivery. Shortly after Jenna gives birth, the static causes her to turn violent against her newborn. Kendall barely escapes the chaos that ensues, witnessing the widespread insanity as reports flood the news. Determined to protect her children, she returns home. Meanwhile, Brent leaves work, feeling bored, unaware of the horror that awaits at home.

Upon arriving, Brent’s paranoia spikes when he finds Carly with Damon, prompting a violent outburst as he knocks Damon unconscious and turns his aggression on Carly. Kendall, affected by the terrifying signal transmitted through her car radio, joins Brent in his disturbed state. In a desperate bid for survival, Carly and Josh flee to the basement, locking themselves in for safety. Brent and Kendall, now united by their chilling desire to harm their own offspring, devise a scheme to poison their children by running a hose from the oven gas to the basement. In a critical moment, Carly, resourceful and quick-thinking, rigs a trap that ignites the gas when they breach the door, resulting in a powerful explosion that temporarily incapacitates both parents.

As chaos ensues, Damon revives and assists Carly and Josh in their escape. However, the situation escalates when Kendall awakens and inflicts a grievous injury on Damon before a series of family conflicts reach a reckless climax. Just as Brent’s parents arrive for dinner, seeking to maintain normalcy amidst the turmoil, they, too, fall prey to the hysteria. This triggers an intense and frantic chase through their home, with Brent losing control and crashing his car, unintentionally bringing more harm to those around him.

The harrowing climax finds Kendall and Brent, now restrained, alongside Carly, Josh, and Damon. The potent influence of the mania still lingers, preventing the children from freeing them. In a moment filled with desperation, Kendall professes her love for her children, begging for release, while Brent ominously trails off with a haunting statement, “But sometimes, we just want to—”, leaving viewers with a gripping ambiguity as the screen fades to black, and the audience is left to grapple with the grim uncertainty of the situation.
