At Ridgewood High, Amy, Frankie, Rachael and Nina formed a deep bond. Now, 15 years after leaving school behind, they're back for a reunion, laughing, reminiscing and chatting how much has changed - and how much hasn't. Nina, once the star of every school play, moved to Hollywood and landed a recurring role on a sitcom. Amy, fondly known as 'the brains of the operation,' is now a Silicon Valley bioengineer. Outgoing and compassionate, Frankie works for a New York publishing house. Rachael, always the most boy-crazy of the crew, married - mostly to please her parents - but is now divorced. All four are strong, successful and somehow, still looking for the right partner. But Frankie has an idea to help solve that - a singles cruise for the holidays.
