Audrey's grandmother used to track down lost items and find their rightful owners. After her grandmother passes away, Audrey, who is striving to make it as an artist in New York, returns home for Christmas. There, she discovers that her grandmother has left her a task: to find the owners of five rings before Christmas. The task also encourages her to seek help from her childhood friend, Finn, who now runs his late father’s private detective agency. Together, they begin the search and soon manage to locate one owner after another, but finding the owner of the final ring turns out to be more challenging than they anticipated.
Perhaps there isn't anything fundamentally wrong with the film, but I find the plot to be weak. Too much of it feels implausible. For example, the order in which they solve the five mysteries is crucial, particularly the last one, yet there’s nothing in the grandmother’s instructions that specifies the order in which they should tackle them. She only says the most important one should be last—but who decides which one is the most important?
