Amazon Studios has just added another drama to its third round of original pilots. This one’s called Hysteria, and it’s an “hour-long character-driven thriller.”

From Amazon’s short description, Hysteria appears to center on some sort of disease or mass panic that’s spreading on Facebook and Twitter.

Amazon says:

Starring Mena Suvari (American Beauty) as “Dr. Logan Harlen,” James McDaniel (Orange Is The New Black) as “Carl Sapsi,” Josh Stewart (The Dark Knight Rises) as “Ray Ratajeck,” Adan Canto (X-Men: Days of Future Past) as “Matt Sanchez,” Laura San Giacomo (Saving Grace) as “Grace Pelayo” and T.R. Knight (Grey’s Anatomy) as “Carter Harlen,” Hysteria follows a doctor (Suvari) who returns to her hometown of Austin, Texas to investigate a growing epidemic that appears to be spreading through social media.

“We’re very excited to be collaborating with Universal Television and Alcon Television Group to bring Hysteria to life for viewers,” said Roy Price, Director of Amazon Studios. “Shaun is known for creating shows with layers of mystery, depth of character and topical themes. His script immediately hooked us and we can’t wait to hear what customers think.”

The Shaun here is Shaun Cassidy, who produced the well-received but short-lived ABC sci-fi series Invasion.

“I can think of no better platform than Amazon to tell a story that explores the price of fear and the very real threat of viral connection becoming contagion,” said Cassidy.

Hysteria is the fourth pilot confirmed for Amazon’s upcoming round. It joins the Jay Chandrasekhar dramedy Really, the Ron Perlman vehicle Hand of God, and The Cosmopolitans.
