An emergency broadcast warns of a zombie virus and orders citizens to shelter. Rosie brushes off her father's fear, claiming a relic charm protects her. On the street a bully taunts a woman in zombie cosplay just before real infected appear and the crowd panics. Families slam doors and flee, but Rosie spots a child and refuses to abandon them. Others shove and accuse her of risking everyone. The infected unexpectedly start dancing and do not bite Rosie, leaving her unharmed. Someone shouts, "Let her go," leaving Rosie caught between angry survivors and the dancing zombies.
A woman is grabbed by a zombie at the scene; someone yells "Let her go!" Panic follows as onlookers shout "A zombie!" and warn "Don't come closer." Others try charms and a hex mirror to repel the supernatural; one mockingly calls it "a vain ghost" while another warns "I eat zombie brains." The seized woman panics, calls for "Mom," and expects to be eaten. After chaos and a last-minute grab—"Got you"—she later declares, "I didn't get eaten." The group is left stunned, the undead threat still unresolved.
A frightened woman bursts into pleas—"Don't eat me!"—when someone offers food at the scene. She insists her flesh is rotten and warns eating it brings death. The person holding the food refuses, saying he'd die if he ate it, and the woman suspects she's being fattened to be eaten, so she vows to stay skinny to survive. An onlooker scolds that dirty hands scared Rosie and, calling her a sweet daughter-in-law, insists on feeding her. The episode ends as they move to force-feed her, leaving her fate unresolved.
Rosie is held by a captor when a caller tells her the man who took her is the Zombie King and only if she bears his child can a child's serum cure the zombie virus. Facing imminent death, Rosie accepts the sacrifice to try to save humanity. The King tests her body—mocking zombie skin's toughness, struggling to "open it," and pressing forward sexually. He declares, "I haven't had a taste of you." The episode ends with him closing in, leaving Rosie's immediate fate and the consequences of her choice unresolved.
Rosie prepares on a bed to have a baby for a zombie. She fusses over boxes of protection and even jokes, "I'm going to have a baby for a zombie," then goes through with it. Afterward onlookers mock the result: the human-zombie baby is called ugly. A man struggles to cover his inability while others scold Rosie for sleeping with a zombie. Someone warns the task isn't for ordinary people. Alone, Rosie looks for a chance to escape, but the episode ends when someone shouts 'Mom!', stopping her and leaving her decision unresolved.
A woman suddenly tells a man she misses her parents and wants to bring him home, but she fears he would refuse. When he unexpectedly agrees—calling it "a free pass to survival"—her relief turns into surprise as bystanders gawk, whispering "so handsome" and even drooling. Her private question, whether she has feelings for him, surfaces amid the attention. The mood shifts from anxious to awkward as they start to leave. She runs after him, shouting "Henry, wait for me," leaving the upcoming visit and everyone’s reactions unresolved.
Rosie returns home with Henry Miller, a pale travel companion she brings before her parents. Her mother and father notice his cold, powder-covered skin and strange pallor but, after teasing that the pair look like a couple, invite him to sit. Rosie explains he was born that way and dodges probing questions. Her father bluntly warns that zombies are everywhere now and food is scarce. Just as the family tries to accept Henry's presence, someone suddenly shouts "Zombie!", and the household's fragile calm collapses into immediate alarm.
Zombies appear outside and, instead of attacking, a horde leaves a pile of supplies at a house. Henry arrives and pretends to have been scaring his parents, explaining that couriers now walk like zombies to blend in; family members exchange uneasy jokes as neighbors note the zombies seem to obey Henry, even whispering he could be the 'Zombie King.' His parents urge him to eat while they examine the haul. Henry shrugs that he has the resources and capabilities, but when they tally everything someone warns, 'It might not be enough,' leaving origin and sufficiency unresolved.
Rosie's family meets Henry to discuss their upcoming marriage. Questions show Henry hasn't spoken since they met and his movements are stiff and zombie-like; Rosie admits she often hits his head. The family, sympathetic but alarmed, decides to press ahead: despite zombies outside they will visit Henry's parents to start wedding plans. Rosie's parents insist and Henry seems to agree. At the episode's end Henry unexpectedly speaks for the first time, leaving the household stunned and the immediate implications of his sudden voice unresolved.
The group is moving when someone tells Henry "safety first" and hands him something. Another voice says, "I'll protect you," and they continue. A bystander blurts, "He's a zombie," questioning why Henry needs protection. They remark they'd seen no zombies on the way and chalk it up to luck. A family member urges, "Dad, Mom, it's too dangerous. Let's get in," and they hurry inside. Just as they think they're safe, zombies suddenly appear — "zombies!" The episode ends with the group facing an immediate threat as zombies appear.
