The episode opens with Kat and Elliot preparing to travel through the pond despite Del’s warnings. Del is deeply uneasy about them returning to 1925, especially on the night of the Lingermore party, but Kat and Elliot believe they may still be able to prevent the tragedy that has haunted Port Haven for generations.
After jumping into the pond, they do not immediately arrive in 1925. Instead, they briefly land in 1979, where they witness a touching moment involving Fern and baby Kat. Fern is introduced to the infant and affectionately calls her “Kitty Kat” before softly singing to her. The moment is calm and warm, contrasting sharply with the danger they are about to face.
Kat and Elliot finally reach 1925 and head toward Lingermore as New Year’s Eve celebrations are underway. The atmosphere is tense because they already know an explosion is destined to happen in the catacombs beneath the estate; their goal is to find Tessa and stop the chain of events before it is too late.
In the catacombs, Elliot finds Tessa and tries to convince her to leave. He reassures her that things do not have to end badly, but the conversation is interrupted when Cliff appears with a gun and orders everyone to freeze. The situation escalates quickly as Tessa reveals she has a gun of her own; the one she previously took from Kat. She points it directly at Cliff while officers shout at her to stand down.
As the confrontation intensifies, Kat is caught in the middle. Elliot sees that she is in danger and rushes toward her, pushing her out of harm’s way. The chaos reaches its peak when the explosion in the catacombs erupts during the Lingermore party; the blast is the very event that later becomes the subject of a folk song in Port Haven.
Back in the present timeline, the episode revisits the season’s flash-forward scene at the pond. Kat, Del, and the other Landry women stand together while Kat says she wishes Elliot were there. Del responds that he is “here in spirit” before they walk away toward a wedding celebration. The scene now carries a much more somber meaning after what happened in 1925.
Another major moment occurs when Fern suddenly comes downstairs and speaks to Tessa in a chillingly direct way. Fern tells her, “This is how it begins, Coop. And I’ll tell you how it ends. You’re going to kill your son.” The statement leaves Tessa shaken and adds dread to the episode.
The story also focuses heavily on Tessa’s emotional state. Through conversations and memories, the episode reveals more about her struggles, her guilt, and the pressure she has been carrying for years. Rather than portraying her as simply reckless, the episode shows how trapped and overwhelmed she feels by the circumstances surrounding her family.
Meanwhile, Jacob learns more about the aftermath of the Lingermore explosion. Rita mentions that there were “so many deaths” connected to the tragedy, which confuses Jacob because the old local song says five people went in and only four came out. Rita explains that four bodies were identified while one was never found. Alarmed by this information, Jacob begins digging deeper into old records and letters.
Jacob later discovers a letter that reads, “Your lie is known.” The message raises new questions about what really happened after the explosion and who may have been hiding the truth. At the same time, his relationship with Abby faces tension because of accusations and lingering conflicts between their families.
By the end of the episode, nearly every storyline is left unresolved. The explosion has finally been shown in full, Elliot’s fate is uncertain, Tessa is emotionally shattered, and Jacob has uncovered new clues about the past. The hour ends with the characters facing the consequences of a New Year’s Eve that changes everything.
