Niles prepares to undergo heart bypass surgery. He is surprised to receive a call wishing him well from Maris, who had learned of his plight from a gossipy acquaintance. Frasier tries to keep Roz and the family at ease by researching the procedure (as well as the doctors' backgrounds) and printing out detailed descriptions for everyone. However, he winds up getting on the surgeon's nerves by questioning his approach to the operation. Martin tries to act as though everything is fine so that he doesn't have to deal with the fear and uncertainty of the situation. Roz tries to help the terrified Daphne stay calm. She refuses to think of other things, stating that she has no future until she knows that Niles is all right. Niles' drug-induced comment about the possibility of hospitals having "memories" about their patients prompts everyone to think back on past experiences in that hospital, from Niles' birth to a time that Roz mistook lipstick on Alice's cheek for a rash. Daphne grows more and more tense as they await word on the surgery. When Martin and Frasier repeatedly bicker about a candy bar stuck in the vending machine, Daphne smashes the machine with a fire extinguisher. She breaks down crying, and everyone does their best to console her. Niles' surgery goes even better than expected, and he begins his recovery. A relieved Daphne is finally able to bring herself to think about their future.
