Martin’s birthday party is anything but a “piece of cake.” Roz is blue because she opted not to attend her family reunion in Wisconsin. Niles is angry because Frasier inadvertently advised one of his callers to dump her current psychiatrist, who just happens to be Niles!

Meanwhile, Daphne is peeved at Martin for not doing his exercises, and Frasier would just like to have some much-needed peace and quiet. But in the middle of Martin’s birthday celebration, a city-wide blackout puts the lights out on the party.

As the evening wears on, Frasier finds himself in the position of counseling everyone. He helps Roz cope with her mixed feelings about her family, gets Niles to admit that he just couldn’t help his patient anymore, and mediates the bickering between Martin and Daphne. Finally, everyone leaves to attend a neighbor’s blackout party -- which leaves Frasier with the peace and quiet he has been seeking.
