Struggling to accept her mother's death, Tig can't let go of Caroline's possessions. Unable to leave home, Tig tries to maintain control of her radio show from Mississippi. Seeing that Tig is unable to accept the fragility of life, most pressingly her own, Bill pushes her to investigate a disturbing, yet oddly hilarious medical procedure.

Bill's cat escapes and he blames Tig for letting her out. Tig's biological father, Mick, leads a search party. Assigned to survey the neighborhood, Tig unearths a secret from Caroline's past. Having found a local station where she can record her show remotely, Tig connects with Kate, the off-beat radio station manager.

Finally feeling better, Tig readies for her return to LA. But before she goes, she is roped into replacing her mother as Mardi Gras Queen at the Bay St. Lucille parade. Remy and Bill are stymied in their search for romance and cats, respectively. Tig searches for Kate at the parade, but instead encounters Jessie, a news reporter who makes her want to stay in town a bit longer.

Tig and Jessie explore the limits of living in the moment. Attempting to connect, Bill attempts to organize a family dinner with Tig and Remy. Remy clumsily pursues a female member of his Civil War reenactment club. Tig and Bill finally have it out over painful events of the past.

Tig returns to Los Angeles and discovers that life has moved on without her. Encounters with friends, an ex-girlfriend, and coworkers all lead her to a crossroads, where a life-altering decision must be made.
