The Oath

When a group of corrupt cops known as The Ravens are arrested, they must induct an FBI mole into their ranks or face prison. It's up to Raven leader Steve Hammond and brother Cole to hide the deal from the gang—including their imprisoned father, Tom—all while playing nice with the Feds.

With Tom's life under threat in prison, Hammond and Cole demand that kingpin Neckbone call off his dogs. All the while, the Ravens must hide the deadly truth about Sleep, both from Neckbone and the Feds. Hammond wields leverage over Agent Byrd, who is pulled ever tighter into the Ravens' grip.

A text message from beyond the grave puts the Ravens on edge. Neckbone uses extreme methods to pressure the Ravens into revealing Sleep's fate. The line between friend and enemy begins to blur for Byrd. Karen Beach's affair with Viper Sam Foster complicates the Ravens' lives in unexpected ways.

Beach's entanglement with Foster grows more dangerous by the day. After a shocking massacre of innocents, Agent Price pressures the Ravens to track the source of WMD, a dangerous new street drug. Neckbone puts his own screws to the gang to uncover this new threat to his business.

Beach hangs Foster out to dry, putting the Ravens and the Vipers in a position of mutual self-destruction. When Sleep's body is found, Neckbone sets a bounty on WMD ringleaders. A newly released Tom stokes discontent with his son's leadership. Winters makes a sneak attack on the Ravens.

Tom's revenge against Winters risks an all-out gang war. With a fresh body on his doorstep, Neckbone gives Hammond a deadly ultimatum. Father and son vie for control of the Ravens, creating a deep gang rift. Hammond and Cole take action to replenish the pension fund, but their plans backfire.

An FBI raid gone wrong takes WMD off the streets but leaves Neckbone out for Raven blood. Agent Price demands Hammond bring his father into the fold by any means necessary. Tom uses a successful heist to assert his precarious power. From hiding, Neckbone begins to exact his revenge.

After Hammond and Cole's worst fears are realized, their search for Neckbone escalates. Byrd pursues WMD's shady connections with big pharma, but gets no help from the Bureau. Agent Price confronts Tom in an effort to flip him. Foster reveals to Beach explosive evidence he stole off Winters.

When Hammond and crew track Neckbone to his hideout, a shocking scene awaits. Just as the Ravens find themselves beset on all sides, yet another enemy comes back to bite them. Foster's play against pharma CEO Shankman backfires. With their back against the wall, the gang must fight for their lives.

In the tense season finale, the Feds descend hard on the Ravens. Hammond is ready to sacrifice himself, but Beach has an ace up her sleeve. Hammond strikes a deal with Agent Price in order to save his crew, but the deal is not what it appears. The Ravens finally square off with Neckbone.
