There’s a heat wave in Seattle, and an ailing Frasier can’t seem to escape a “wave” of r ising tensions a ll a round him. Roz a nd Bulldog are bic kering at the radio station, while Daphne and Sherry are getting on each other’s nerves at home.

Why are Sherry and Daphne feuding? First, it’s because Sherry keeps trying to tell Daphne how to run the household. Later, Daphne becomes fed up with Sherry’s attempts to fix her up on blind dates with every man she meets. In a rush of anger, Daphne decides to “escape” to Niles’s apartment. But when she unexpectedly announces that she’s spending the night, Niles passes out!

After Niles recovers, blaming his fainting spell on the lack of air conditioning in the building, his evening with Daphne really starts to “heat up.” She slips into his silk dressing gown, and he brings out the champagne. Just as Niles is panting over Daphne’s suggestion that they sleep together in the one room with a fan, they must return to Frasier’s apartment to retrieve her medication. Niles’s hopes for the night are dashed when Daphne and Sherry make up after realizing that their animosity toward one another stems from the competition they feel for Martin’s attention.
