Don’t underestimate Patty.  Netflix has released the official trailer for Insatiable, its dark comedy starring Debby Ryan, Dallas Roberts and Alyssa Milano, from writer Lauren Gussis (Dexter, Once Upon A Time), Ryan Seacrest Productions and Storied Media Group.

For years, Patty (Ryan) has been bullied, ignored, and underestimated by those around her because of her weight. But now that she finds herself suddenly thin, Patty is out for payback against anyone who has ever made her feel bad about herself. Bob Armstrong (Roberts), a disgraced attorney whose true passion is coaching beauty pageant contestants, is the only one who sees Patty’s potential, and takes her under his wing — first as a legal client, and then as a pageant contestant whom he coaches toward becoming the top pageant queen in the country. But Bob and his wife Coralee (Milano) have no idea how deep Patty’s rage goes, or how far she will go to exact revenge on anyone who has ever wronged her. Bullies beware: payback’s a bitch, revenge is sweet, and if you cross Patty, you’ll be her next treat.

Cast also includes Christopher Gorham as Bob Barnard, Erinn Westbrook as Magnolia Barnard, Michael Provost as Brick Armstrong, Kimmy Shields as Nonnie, Irene Choi as Dixie Sinclair, and Sarah Colonna as Angie.

Insatiable is produced by CBS TV Studios. Gussis executive produces with Ryan Seacrest, Nina Wass, Andrea Shay, Todd Hoffman, Dennis Kim, and Andy Fleming.

Insatiable launches August 10 on Netflix.
