Shannon O'Connell is broken. She is sixty-five years old and looks twenty years younger - there's not much that makes her happy. Her partner of thirty years left her for a mutual friend offering only the cliché "I love you, but I'm not in love with you." Her mother is disappearing before her eyes with dementia. And now, the death of her best friend - Linda - from metastatic breast cancer brings her to her knees. In this dark night of the soul - filled with endings -- she could not have predicted that this moment could be a beginning. The "Tribe," Linda's group of lifelong friends, gather at Shannon's family's beachside resort to celebrate her life as they have for countless celebrations over the years. And while Shannon finds comfort in their company, it is an old flame, the beautiful and sexy Elizabeth Matthews, who awakens something in her that was forgotten long ago. Can they overcome the emotional roadblocks they put in their own way? Will falling in love again make this Third Act the best one of all?
