In the small New Orleans neighborhood of Treme, they are about to celebrate the first "second-line parade" since the town was struck by Katrina and many of the local musicians and residents are reunited, but even more have not yet returned.

As the city celebrates the return of many displaced residents with another second line parade, Albert presses a Councilman to reopen housing projects and Davis recruits some local musicians to put out a campaign CD.

Toni seeks help from a former cop in helping her figure out Daymo. Albert is angry about the lack of lodging, while Davis raises his profile with a television appearance.

Davis concocts a remedy for the post-Mardi Gras blues; Annie makes a decision that Sonny takes personally; Janette’s latest chef’s gig gets bogged down; Antoine becomes LaDonna’s unexpected benefactor; Colson warns Albert to avoid trouble on St. Joseph’s night; Creighton is inspired by a classic novel set in old New Orleans.
