The death of Sue Florek, a beloved mother figure, brings Percy Fraser back to a place that has haunted her for a decade: Barry's Bay. As she faces all the people and secrets she ran from years ago, she wonders if returning was a mistake. Honoring Sue and seeing Sam Florek-the great love of her life-brings back beautiful memories of her first summer at the lake, but also the pain of all she's lost.

The Tavern raises tensions between the brothers. Jordie introduces Chantal to lake life, and catches Delilah in a lie. Meanwhile, Percy starts to realize she came here for more than just Sue. Reconnecting with Sam makes her remember her second summer in Barry's Bay, when a game of Truth or Dare changed everything.

Delilah tells Jordie her secret, Chantal enlists Charlie's help with a crisis, and Percy and Sam spend more time together-which quickly feels like playing with fire. It's almost like high school all over again... like that summer of the power outage and the bonfire party, where hormones were raging and emotions were high.

Sue's will reading leaves everybody in shock. While Sam and Charlie are furious, Percy is utterly lost. She, Delilah, and Chantal admit some hard truths to both each other and themselves, and Percy wonders whatever happened to the girl she once was... the girl who wrote scary stories, swam across the lake, and wasn't afraid to go after what-and who-she wanted.

Drew shows up with an unexpected guest. Meanwhile, Delilah and Charlie reach a crossroads, and Sam makes a life-changing decision-prompting Percy to do whatever she can to distract from her own feelings. Yearning and jealousy are in the air-just like at that New Year's Eve Party in 2015, when Percy's plus one caused a stir, and an unlikely pair shared a midnight kiss.

Percy's shocking secret is out, and everyone's caught in the fallout. An unlikely trio forms a search party, while Percy puts her own drama aside to be there for Delilah and make up for past wrongs. As Percy and Sam fall apart in the present, we see how they fell head over heels in love for the first time as teenagers.
