Plot

Sarah invites her childhood friends, Louise and Abby to a remote island that they once spent time at in their youth, in hopes of bringing their distant group back together. Though Abby and Lou are reluctant, they go with Sarah to the island. While there, they use a hand-drawn map to try to find a time capsule they had buried as kids. They give up after Abby picks a fight with Louise over Lou having slept with her boyfriend years ago, something Abby has never gotten over and which ruined their friendship.
