On the eve of her wedding, Daphne's torn between the man she loves and the man she's engaged to marry.

After running off together, Niles and Daphne face the wrath from their jilted lovers: Donny's suing for emotional distress and Mel's plotting a ruse.

Daphne considers dumping Niles after Donny and Mel's plotting stresses her out. Fortunately, Frasier comes to the lovers' aid once again.

When Daphne and Niles decide to move in with each other, Daphne's mother and Simon arrive on a surprise visit. Daphne and Niles decide to put off moving in together until her visiting relatives are gone. Meanwhile, Frasier feuds with Cam Winston, his neighbor, over where Cam parks his large vehicle.

Daphne and Niles continue to try and hide the fact that they have moved in with each other from Mrs. Moon. She makes such a mess of things that the only way she will leave is if Simon takes care of her, but Simon has left for California. Meanwhile, Frasier's neighbor Cam drapes the American flag over his balcony, and Frasier cannot complain because it would seem unpatriotic.
