Defiance is set on a United States Marine Corps base in North Carolina in 1971. Two officers, one black Chris Chalk and one white Stephen Lang, are on a collision course over race, women and the high cost of doing the right thing. In addition to Chalk and Lang, the cast includes Chris Bauer, Trevor Long, Margaret Colin and Jeremy Strong. It is the second play in a planned trilogy for Shanley, which started with Broadway's Doubt.
