She's a bada$$. A woman with a gun on her hip and a badge on her belt. And she's good with a gun. Very good. She's dying to be a member of the unit - literally. Special Agent Kathryn Hanko soon finds out what it takes to join the clandestine law enforcement team known only as "the unit". Enduring a rigorous intake procedure, she fights through her anxieties over being the only woman in an otherwise all-male elite team. She cusses, she demands to be considered an equal to the point of taking "Hank" as her code name, and she drives herself to make sure she is an equal to the men around her. She doesn't want to be the team's weak link. Her arrival heralds the start of changes for the team and how they interact. Past rules that were obeyed without question are now challenged. The changes that ensue solidify the team she is now part of as the team's sniper and firearms expert. Does she make the grade? Of course she does, and faces her first mission with them against the terrorist group Camp Chaos.
