Courtney Sullivan's Maine is a family saga about three generations of Kelleher women—matriarch Alice, her daughter Kathleen, daughter-in-law Ann Marie, and granddaughter Maggie—who gather at their beloved, but fading, family beach house in Maine, confronting long-buried secrets, regrets (especially Alice's guilt over her sister's death), alcoholism, marital strife, and new challenges like Maggie's unexpected pregnancy, revealing the complex, often messy, but enduring bonds of family as they face losing their summer haven.
