While trying to rescue Professor Pheasant from a nuclear-glass prison, 99 tells Max she's pregnant. Max gets so excited he tells a reporter that he's a spy and blows his cover, rendering him useless as an agent. When CONTROL figures out that the only way to break Professor Pheasant out of the glass is to have The Singing Agent Rosa LaCosta sing a special note that can shatter glass. With no other agents available, Max is forced to have his face changed to work on the case. He then sneaks into KAOS headquarters as the accompanist to opera singer Rosa LaCosta.

Two good cameos from Martin Landau and Phyllis Diller bring this one up a notch.
