When Frasier (Kelsey Grammer) is booked on a celebrity cruise, it naturally follows that Niles (David Hyde Pierce), Martin (John Mahoney), and Roz (Peri Gilpin) will go along for the ride. Niles in particular is looking forward to the tranquility of a sea voyage on a luxury liner (which truth to tell isn't so luxurious) so that he can expunge the memory of his estranged wife Maris. Imagine Niles' reaction when he spots Maris amongst the passengers -- and she's got some bad news for him. ~ Hal Erickson, Rovi
