Travel writer Nina Kerensky refuses to give up her freedom for any man, but she wants her grandmother to be happy. So to allay Gram's fears that the fulfillment of love and marriage are passing Nina by, she creates an imaginary husband---a sexy surgeon named Steve. Now Nina's adrift on a sea of well-meaning deception. Grams, anxious to finally meet her elusive grandson-in-law, plans to "surprise" Nina by showing up on the cruise the happy couple are supposed to be taking. Nina needs a husband--fast! Veterinarian Steve Tabor is out of the husband business. He wants no part of any woman who tells whoppers--he had enough of that from his faithless ex-wife. But sweet and fun--loving Nina really floats his boat. He can't turn down the prospect of being her shipmate for seven days and seven nights. Pretending wedded bliss is not all smooth sailing. Rough waters lie ahead for the couple pretending to be honeymooners, especially for a vet posing as "plastic surgeon to the stars." Nina and Steve ride through wave after wave of missteps and close calls on their cruise for love.
