Online streaming service Sony Crackle has released the season two trailer of its original drama series The Oath, which returns Feb. 21.

The series, executive produced by Curtis "50 Cent' Jackson and Joe Halpin, explores a world of gangs made up of law enforcement officers, according to Crackle. 

The series stars Ryan Kwanten (True Blood), Cory Hardrict (The Outpost, American Sniper), Katrina Law (Sacred Lies, Training Day) Christina Milian (Be Cool, Grandfathered), J.J. Soria (Animal Kingdom, The Fosters), Leona Lewis and Kevin Connolly (Entourage).

Sony Crackle has ordered a second season of gritty drama The Oath. the SVOD service said at its upfront presentation in New York Tuesday (April 24).

Curtis “50 Cent” Jackson executive produces the show, which was created by Joe Halpin.

The Oath is the network’s most-watched new original series and has the highest retention rate, episode to episode, of any Sony Crackle original, the service said. 

Exploring a world of gangs made up of those sworn to protect and defend, the series “sheds light on corrupt and secret societies that are nearly impossible to join — only a select few make the cut — but once inside, members will do what they must to protect each other from enemies on the outside and from within their own ranks,” in Sony Crackle’s words.

“Our audience has truly responded to this authentic, raw and compelling series,” said Eric Berger, chief digital officer, Sony Pictures Television Networks and general manager, Sony Crackle. “Thanks to Joe, 50 Cent and our stellar ensemble and production team for bringing this powerful story to life. We look forward to taking the next step together.”

Season one featured Sean Bean, Ryan Kwanten, Cory Hardrict, Katrina Law and Arlen Escarpeta in the cast.

“The Oath has been one of the highlights of my professional career as a writer, so having the opportunity to take our storytelling to that next level is incredibly exciting,” said Halpin. “Sony Crackle, 50 Cent and the entire cast have been amazing collaborators. We have so much more story to tell and I can't wait to get started.”
