XX (2017) Timeline Explained – Every Event in Order

The contents of the red box are never revealed on screen, and that ambiguity is the point of the segment. When Susan finally asks Danny what was inside, he simply replies, "nothing," suggesting the box may have been empty or that whatever it contained was something the human characters could not articulate. The horror of XX's opening story lies in this unanswered question, since whatever Danny saw was powerful enough to make him, his sister, and his father all refuse food until they starved to death.

Foreshadowing: Danny's immediate refusal to eat after peering into the box on the train is the first clue that the encounter has fundamentally altered him.

Whatever Danny saw inside the red box appears to have given him an idea or compulsion that he then spread to the rest of his family. After the train encounter, Danny stops eating, and after a private conversation with his sister Jenny, she begins refusing food as well. When Danny whispers something into his father Robert's ear, Robert also loses the will to consume food, suggesting the "curse" of starvation is transmissible through the secret Danny learned. The family ultimately dies of starvation in the XX anthology, with each member wasting away while appearing indifferent to their own deterioration.

Foreshadowing: The family's gradual emaciation by Christmas is foreshadowed by Danny's five-pound weight loss at the doctor's office shortly after the train ride.

The film never reveals exactly what Danny whispered into his father's ear, but the effect is immediate and identical to what happened to Jenny after she spoke with Danny. This suggests Danny shared whatever he saw inside the red box, passing the same compulsion to refuse food from one family member to the next. The secret functions like a contagion in XX, and Robert's sudden refusal to eat shows that knowledge of the box's contents is enough to override basic survival instincts.

Mary chooses to conceal David's corpse rather than call emergency services, and the segment never gives a fully logical explanation for her decision. The panic of protecting her daughter Lucy from the trauma of discovering her father dead, combined with denial and the social pressure to keep the party going, seems to override Mary's rational judgment. The XX segment uses this irrational choice to build escalating dread, since every minute Mary spends hiding the body makes the eventual discovery worse, culminating in the body collapsing into the birthday cake.

When the panda costume collapses into the cake and the head comes off to reveal David's body, the children scream and the segment's full title appears on screen: "The Birthday Party, or, The Memory Lucy Suppressed From Her Seventh Birthday That Wasn't Really Her Mom's Fault (Even Though Her Therapist Says It's Probably Why She Fears Intimacy)." This extended title reframes the entire XX story as a repressed childhood trauma rather than a straightforward horror plot, suggesting that the real horror lives on in Lucy's adult psyche, where it has shaped her relationships.

Foreshadowing: The very first shot of Mary's discovery of David's body implies this trauma will define Lucy's entire future.

The creature in "Don't Fall" resembles the evil spirit depicted in the ancient cave painting the group discovered earlier in the day. After attacking Gretchen at night, the being literally wears her skin as a disguise, allowing it to move among the remaining friends Paul, Jess, and Jay without raising suspicion. This skin-walking mechanism is what makes the XX segment feel like a slasher, since the entity can strike from inside the group at any moment before it kills Paul and Jay and pursues the injured Jess.

Foreshadowing: The cave painting the group discovers before camping is a direct preview of the entity that will hunt them that night.

"Don't Fall" is presented as an unofficial sequel to Roman Polanski's Rosemary's Baby, tying it into a wider horror mythology within the XX anthology. The cave painting and the ancient spirit that emerges suggest the demonic lineage from Rosemary's Baby has spread beyond the original story, with the entity now operating in remote deserts far from New York. The connection implies that the horror of Rosemary's Baby was never an isolated incident but part of a much older, ongoing supernatural pattern.

The XX story establishes from the beginning that Cora went into hiding while pregnant at the suggestion of a doctor, and the mailman Chet later hints that her husband, a distant actor, is unlikely to be Andy's biological father. As Andy nears his eighteenth birthday, his voice deepens and his fingernails and toenails grow into claws, while his school principal appears entranced by him. Andy ultimately confirms what Cora has long suspected: he is the spawn of Satan, conceived through a demonic bargain Cora made before his birth, mirroring the setup of Rosemary's Baby.

Foreshadowing: Andy's violent outburst at school, where he tears off a classmate's fingernails, foreshadows the demonic transformation he will soon complete.

Cora spent Andy's entire life in hiding specifically to protect him from Satan's claim on his soul, so when the moment of surrender arrives, she chooses to honor that sacrifice. Rather than bowing and giving Andy over, she embraces him and explains why they went into hiding, asserting that her love for him outweighs his demonic destiny. Her conviction moves Andy to choose his mother over his dark inheritance, though Satan responds by violently killing them both in XX's bleakest finale.

Foreshadowing: The entire premise of Cora living under a false name foreshadows that her maternal devotion will ultimately be the force she relies on to defy Satan.

The walking dollhouse with the blinking face and the scurrying detached hand serves as the surreal stop-motion framing device that bookends the four horror stories in XX. Inside it, biological functions like a stomach, sewing needles that craft tapestries, and a morphing apple-heart suggest the dollhouse is a miniature living organism. The dollhouse places a blackbird inside an unconscious girl's chest through a small door, after which she awakens, implying the framing device is birthing or animating the human hosts whose stories we then watch.

Foreshadowing: The opening dollhouse segment plants the idea that the people in XX's stories are being assembled or awakened by something beyond their understanding.

After Danny, Jenny, and Robert all die of starvation, Susan is left alone with no explanation for why her family refused to eat. She believes that understanding what was inside the red box is the only remaining thread connecting her to her lost husband and children, since whatever Danny saw there is what took them from her. Searching the trains has become Susan's way of mourning in XX, a desperate attempt to recover the secret her son carried to his grave.

Foreshadowing: Susan's haunting dream of her family eating her at the dinner table hints at the obsessive grief that will define her life after their deaths.

The dollhouse first tries placing the small blackbird inside a baby doll, but removes it when the doll immediately cries, then transfers the bird into an unconscious girl through a small door on her chest. After some time the girl awakens, suggesting the bird functions as a soul or animating spark that brings the doll's inhabitants to life. Whether the bird is a real dead creature or a stuffed toy is left ambiguous in XX, reinforcing the framing device's unsettling, dreamlike logic.

Foreshadowing: The earlier failed attempt with the crying baby doll foreshadows that only a body quiet enough to accept the bird will be successfully animated.
