Jessica Biel is set to star in the upcoming thriller TV show, The Sinner, and she already looks spooked.
The 34-year-old actress posted a photo of herself nervously reading a script for the USA series, with the caption: "Back to work. I'm not actually reading anything. I'm just privately hyperventilating. #TheSinner."

The Sinner -- based on Petra Hammesfahr’s book of the same name -- is an hour-long drama about a young mother (Biel) who is trying to figure out what is causing her to have violent tendencies. An rogue investigator (Bill Pullman) becomes fascinated with uncovering the motive behind these inexplicable fits of rage, and the two soon start working together to unearth what it is from her past that is causing such behavior.
Biel is also an executive producer on the show.
The series marks the actress' return to TV as a series regular. She got her start on 7th Heaven in 1996 and left the long-running family show in 2006.

ET was with the actress during her first season on 7th Heaven, and given her excitement to be on set back then, it's no wonder she's making a return to TV. "Coming to work is so cool," she told ET in August 1996. "Because everyone is so cool and nice."
