The Revolutionary War reaches its final 'Turn' of the season as the AMC period drama heads into "The Battle of Setauket," and Abe Woodhull (Jamie Bell) faces all-out war to keep the Culper Ring alive. Before Sunday's all-new season finale installment brings things to a temporary halt, we have an exclusive first look at the latest AMC episode to 'Turn' the tide in "The Battle of Setauket."

Our exclusive first look at this Sunday's final 'Turn' installment of the season sees Major Hewlett ('Game of Thrones' star Burn Gorman) putting on his best Grand Moff Tarkin by giving the order to fire on the Brits' own store of gunpowder, rather than allow it to fall into rebel hands. Simcoe (Samuel Roukin) is none too thrilled with the turn, so could a rift between the British officers be in the cards for the finale?

Meanwhile, here's what AMC had to say of Sunday's finale event, "The Battle of Setauket":

Ben and Caleb lead a raid on Setauket to save the Patriot families. Mary grapples with the realization that Abe is a rebel spy.

Only one episode remains until AMC's 'Turn' comes to an exciting first season conclusion, so what say you? Will Abe manage to best Major Hewlett now that it's come to all-out war? Check out our exclusive clip from Sunday's finale "The Battle of Setauket" above, airing 9:00 p.m. EST/8:00 p.m. CST, and give us your finale predictions in the comments!
