Mercy's Muslim women protest co-ed swimming classes at the local pool. Mayor Popowicz refuses to change the rules, nervous at what voters will think if she's seen kowtowing to the Muslims.

In the end, the pool remains integrated, but Fatima dons an outrageous bathing suit to ensure she remains fully covered.
