"The Attackman" refers to the players on a Lacrosse team positioned to score the most points in this aggressive sport. And Lacrosse means everything to Jordan Simms and Chris Wheatley, two high-school seniors from different religious traditions who come to realize, as a life-changing game nears, that their parents' values aren't the same as their own.
