The episode "Clan of the Cave Mom" begins with a field trip from Springfield Elementary to the local anthropology museum. The students watch a 4D film about prehistory, which includes effects like cold wind blowing on the audience. Marge Simpson, acting as a chaperone, is distracted by her phone and is shushed by Principal Skinner, who reminds her that the children are trying to learn.

During the lunch break at the museum, Milhouse Van Houten tells Bart Simpson that his father, Kirk, was injured at his new job when he got pinned between the ice rink and basketball court during installation. As part of his settlement, Kirk received tickets to a concert by a Hispanic rap group. Milhouse invites Bart to attend the concert with him.

Bart attempts to call Milhouse's mother, Luann Van Houten, to persuade Marge to let him go to the concert. However, this backfires because Luann is upset with Bart, having recently told him directly that he is a bad kid. This causes tension between Marge and Luann, escalating into a feud.

The conflict between Marge and Luann intensifies as they compete to secure the best seats for their sons at the upcoming concert. Both mothers engage in escalating actions to outdo each other, driven by their protective instincts and rivalry.

Parallel to the present-day story, the episode cuts to a prehistoric setting 20,000 years ago, where the Simpson family is depicted as cavemen struggling to survive. Marge, in this ancient timeline, takes on the role of a hunter and provider. She kills a snake with a rock to feed her family, demonstrating her protective and resourceful nature.

The prehistoric Simpson family faces a dire threat from a giant blue-haired wolf. The family must work together to defend themselves and survive the attack. The sequence shows detailed steps of their struggle, including Marge's leadership and the family's coordinated efforts to fend off the predator.

Throughout the episode, the prehistoric scenes are animated in a distinct style inspired by the animated series Primal by Genndy Tartakovsky, contrasting with the usual Simpsons animation style used for the present-day scenes.

Back in the present, the feud between Marge and Luann reaches a climax. Marge confronts Luann about her harsh words to Bart and the ongoing competition over the concert tickets. The confrontation reveals the emotional stakes for both mothers, who are fiercely protective of their children.

Bart expresses his feelings during this conflict, telling Marge that while he can handle being a "bad kid," he cannot handle losing the one good parent he has. This moment highlights Bart's emotional vulnerability amid the parental dispute.

The episode concludes with a resolution of the feud, though the exact details of how Marge and Luann reconcile or settle their differences are not explicitly detailed in the sources. The prehistoric storyline ends with the Simpson family surviving the wolf attack, reinforcing the theme of family protection and survival across time.

Overall, the episode intertwines the modern-day parenting conflict with a prehistoric survival story, using parallel narratives to explore themes of family, protection, and rivalry. The prehistoric sequences provide a dramatic and stylistic contrast to the comedic present-day storyline, culminating in a layered narrative about maternal instincts and family bonds.

At the end of "Clan of the Cave Mom," Marge and Luann Van Houten resolve their feud after a fierce competition to secure the best concert seats for their sons. Meanwhile, the prehistoric Simpson family survives a dangerous encounter with a wolf, which they ultimately tame and integrate into their group. The episode closes with the modern family enjoying the concert, but Marge reflects on her overprotective behavior and its impact on Bart.

Expanded narrative of the ending scene by scene:

The episode culminates with Marge and Luann locked in a tense rivalry over getting front-row tickets to a concert for their sons, Bart and Milhouse. After a series of escalating confrontations, Marge finally secures the coveted seats. However, as they arrive at the concert, Marge experiences a moment of self-awareness when someone points out how her aggressive behavior has affected her family relationships. Bart expresses his feelings, telling Marge that while he can handle being a "bad kid," he cannot handle losing the one good parent he has. This emotional exchange leads Marge to realize that her overprotectiveness and competitiveness have strained her bond with Bart.

Parallel to this, the episode's prehistoric storyline, animated in a distinct style inspired by Genndy Tartakovsky's Primal, shows the Simpson ancestors facing a life-threatening situation with a giant blue-haired wolf. Initially, the wolf is a threat, but after it is injured by a falling rock, the mother figure chooses to rescue and care for the wolf rather than kill it. This act of compassion leads to the wolf becoming a part of their family group. The prehistoric Simpsons then share a meal that includes the wolf, symbolizing their survival and adaptation.

In the final moments, the modern Simpson family is shown enjoying the concert with the best seats, but the victory feels bittersweet for Marge. She reflects on the cost of her actions, acknowledging that her fierce protectiveness may have caused more harm than good. Bart's emotional plea underscores the episode's theme about the balance between parental care and allowing children independence.

Regarding the fate of the main characters at the end:

• Luann Van Houten ends the feud with Marge, though the rivalry leaves a mark on their relationship.
• The prehistoric Simpson family survives their ordeal, having tamed the wolf and integrated it into their group, symbolizing resilience and cooperation.

This ending ties together the modern-day family drama with the prehistoric survival story, highlighting themes of protection, family bonds, and the consequences of overprotection.
