The actress stars as a Senate investigator searching for her sister's killer on USA Network's new noir series, Briarpatch, and only ET has an exclusive first look.
"Allegra Dill, a dogged Senate investigator, is drawn home to her existentially corrupt hometown to investigate the murder of her sister, a homicide detective," explains showrunner Andy Greenwald in the clip, as we get our first look at Dawson's no-nonsense character.
"I play Allegra Dill. She is a woman on the hunt," Dawson adds. "She's completely suspicious from the get."
On Briarpatch, everyone's a suspect, with Allegra -- and the viewers -- not knowing who to trust. "[It's] really fun and makes for a lot of really insane situations," the actress promises.
Allegra doesn't get the warmest of welcomes from the citizens of her old hometown of San Bonifacio. "People want her to be on her way," says Brian Geraghty, who plays Gene Golder.
"It starts off as a murder mystery," adds Alan Cumming, who plays Clyde Brattle, "but very quickly becomes something completely different."
"Why have one plot when you can have two or even three?" Greenwald asks, as it becomes clear the show's plot will take twists and turns.
"It's a weird and funny, intense wild ride," Dawson teases.
