Commander Steve McGarrett and Lieutenant Catherine Rollins have been through a lot. But nothing they trained for in the Navy has prepared them mentally for what's yet to come. When times get tough, they are pushed to their limits, and they need each other more than ever for support. But will they let each other in or put on the Navy brave face? These people tormenting them only have one thing on their agenda: hurting Doris McGarrett. And they'll do anything to do it. Even kill her son's only chance at true love.
