Six Feet Under: Familia (2001)

Synopsis
Following the burning of the abandoned house across the street, the Fishers wonder if Claire (Lauren Ambrose) might be the mystery arsonist. In the midst of the arson investigation, Brenda (Rachel Griffiths) makes an appearance at her first dinner with the family, but her desire to make a good impression on Ruth (Frances Conroy) is severely compromised when Ruth discovers her and Nate (Peter Krause) in a somewhat graphic situation. Meanwhile, the family grapples with the funeral arrangements for a murdered Mexican-American gang member, from whom David (Michael C. Hall) mines some unexpected courage that helps him end an argument with Keith (Mathew St. Patrick). ~ Rebecca Flint, All Movie Guide
