Tripplehorn plays Barb Henrickson, first and only legal wife, in this HBO drama from creators Mark V. Olsen and Will Scheffer. The Henricksons are polygamists living in Utah and the series follows their lives, both triumphs and challenges. Co-starring Bill Paxton, Ginnifer Goodwin, and Chloë Sevigny. Tripplehorn speaks on the tone of the show:
I think it’s a really grounded humor. We have to pull ourselves back. When we’re trying to be funny it doesn’t work.
