A tragedy reunites Claire with a guy who sullied her reputation at school; David and his new boyfriend run into Keith and his new partner on the disco circuit; and Ruth has an eye-opening camping trip with Hiram.

Ruth takes a personal interest in the death of a woman who has no friends or relatives. Meanwhile, Brenda's search for a literary muse prompts her to turn to one of her massage clients--a prostitute named Melissa--and Nate's relationship with Brenda takes an unexpected turn.

Fisher & Diaz deal with the recently discovered body of a man missing for years. Meanwhile, Ruth sets the ground rules for a new live-in apprentice named Arthur, David meets an old acquaintance during an L.A. Gay Men's Chorus rehearsal, and Claire is surprised by her responsibilities as Olivier's new assistant.

Meanwhile, the Fishers decide to hold a yard sale; David grooms Arthur for a new role; Nate gets intimately involved in Maya's afternoon playgroup; Claire attends an art party; Ruth and George receive some unwanted wedding gifts; Federico gets caught up in family responsibilities; Keith adjusts to the peculiarities of his new job; Joe isn't thrilled by Brenda's yearning for normalcy; and some important memories go up in smoke.

Claire is seduced by Billy's lust for life but hits a roadblock trying to fund the next leg of her educational journey; George is haunted by visions of an early trauma; Brenda feels at home with her new supervisor Jackie; David and Keith meet a fertile young woman named Mary; Vanessa encourages Rico to mingle, so he does--at a funeral directors' conference.
