Daniels pays Archer a surprise visit with news of a Xindi plot, as three reptilians travell back 150 years in time to 21st century Detroit. Someone needs to stop them.

Antoine's students show interest and Annie's demo hits its mark; Sonny and Linh show interest, but no marks are hit; L.P. Everett's new case has smoke and fire; heat at the in-laws' house forces LaDonna to move; Hidalgo discovers a new angle; Janette's resistance slips; Albert learns he has chronic obstructive pulmonary disease.

As New Orleans gears up for its first Fat Tuesday since Katrina, Albert is sent a less-than-celebratory message by the NOPD. Sonny leaves Annie to her own devices; LaDonna puts her bad news on hold; the Bernettes make a Mardi Gras appearance, though Creighton's heart isn't really in it.

Toni tracks down a former cop in search of clues about Daymo; Davis raises his profile on the streets and on TV; Delmond tours while Antoine toils; Janette considers suspending operations; Albert vents about the lack of tribe lodging; Sonny crosses a line with Annie; the Bernettes make a splash at the Krewe du Vieux parade.

Albert presses Councilman Ron Singleton to reopen housing projects; Davis enlists some top local musicians to cut a campaign CD; a Japanese jazz fan does a good turn for Antoine; Janette cooks for four celebrity chefs; Annie fails to embrace Sonny's houseguest; the city celebrates the return of displaced residents with a second-line parade.

Desautel's on the Avenue opens softly. Sonny pawns instruments to buy jewelry. LaDonna Batiste-Williams gets threats from a stranger and support from Albert Lambreaux. Sofia Bernette gets evicted for her own protection. Terry Colson finds a case collapsing and his popularity declining. Desiree confronts Robinette.
