At a tense campsite, a group argues over mysterious sounds inside a tent, with one insisting someone is inside—possibly a woman’s lover—while others blame it on the wind. The conflict escalates when a man jokes about a mouse crawling in, provoking anger from a woman named Tilly. Another woman, Helen, tries to defuse the situation, but Tilly grows hostile, accusing Helen of wanting to kill her. The episode ends with Tilly threatening to attack the unseen intruder, leaving the true presence inside the tent uncertain and the group on edge.
