Told alternately from the perspectives of Jeremy and Dana, a pair of friends with a long history and now turning 30, Mother's Day follows these two through a weekend back in their home town. They are visiting yet another dying mother of a classmate, bizarrely the seventh in this tiny group to be stricken before the age of 60--most well before. But the weekend becomes much more about their own issues and relationships as they deal with their past and try to figure out what it means to be a grownup.
Jeremy is completely without direction and generally content that way. He is estranged from his father and brother, in a soulless job and leads a life nearly devoid of personal relationships. Over the weekend he will encounter more romantic entanglements than he has faced in all of the previous year, and he will have to decide what he really thinks of his larger-than-life father.
Dana is an ambitious career woman with a close relationship with her father and a loving marriage. But her mother's passing, just a year before, is still very fresh for her. That sense of loss is now compounded by her husband's breakdown and mental illness. This weekend she will face a moment of truth in her marriage that will either help her turn the corner or send her around the bend.
These two friends will get to know each other again over the weekend, including revisiting a secret they share but about which they are both conflicted. They also will get reacquainted with their families and some odd small town characters. But more importantly they will learn how to get through their respective mid-life crises that have arrived a little early.
