Septuagenarian matchmakers the "Shippers" are on a mission to secure Mr. Right for Abby O'Brien, a sunny, optimistic childcare worker for Monarch Cruises. Divorced elitist lawyer Spencer Randolph Masterson's goal on the MS Buckingham is to persuade his mother, Daisy, to leave her ridiculous cruise ship lifestyle and return to New Orleans. But Daisy isn't interested. Besides, she and her matchmaking posse have a marriage to arrange. When a secret from Daisy's past surfaces and threats of blackmail start flying, the Shippers must protect their own while attempting to convince Spencer's scarred heart to weigh anchor and boldly set sail for a future with Abby.
