In a Variety exclusive teaser for AMC’s upcoming Revolutionary War spy drama, “Turn,” viewers get a look at the characters that make up the Loyalists.

“Pirates of the Caribbean’s” Kevin McNally plays Richard Woodhull, a staunch loyalist and a judge magistrate.

“Richard believes in law and order and doesn’t see how a nation without a king can effectively govern itself,” executive producer Craig Silverstein says in the clip.

This puts him in direct conflict with his son Abraham Woodhull (Jamie Bell), a member of the Culper Ring spies working for General George Washington during America’s War of Independence.

“Abe believes he should be in a free country and Richard believes it’s OK to be royal subjects,” Bell says.

Viewers also get a look at the villain of the series, Lt. John Simcoe, who enforces the occupants of the crown.

Samuel Roukin who plays Simcoe, said, “He has his own set of rules and he makes sure who he requires to toe the line is toeing the line.”

The almost five-minute long video describes the rest of the Loyalists: John Andre (JJ Feild), who heads the British intelligence, Britain’s Major Richard Hewlett (Burn Gorman), and Robert Rogers (Angus Macfadyen), the head of the Queen’s Rangers military unit.

“This is going to be a show that hopefully really intrigues, in a sense of learning about, of how the country was really formed,” executive producer Barry Josephson says.

“Turn” will premiere at 9 p.m. April 6 on AMC.
