The Sundance hit Zipper got its first trailer this week.

Here’s the official synopsis for the political drama:

Sam Ellis is a man on the rise – a federal prosecutor on the cusp of a bright political future. But what was meant to be a one-time experience with a high-end escort instead turns into a growing addiction. His moral compass unraveling, his new demon threatens to destroy his life, family and career.

Patrick Wilson (The Conjuring) stars as Sam Ellis, while Lena Headey, Dianna Agron, Ray Winstone, John Cho, and Richard Dreyfuss round out the rest of the ensemble.

Zipper marks Mora Stephens’ second feature film after 2005’s Conventioneers. Stephens wrote and directed the project.

Zipper hits theaters and Video on Demand on August 28.
