The 10th season of HAWAII FIVE-0 finds McGarrett (Alex O'Loughlin) and Five-0 reeling from the shots fired in HQ and who on the team was hit. Once the smoke clears, some familiar faces such as Steve's mom, Doris McGarrett (Christine Lahti) and imprisoned hacker Aaron Wright (Joey Lawrence) return and we meet some new allies in the task force's quest to wipe out the crime that washes up on the island's sun-drenched beaches. Whether Danny (Scott Caan) pesters McGarrett about his failed love life, Junior (Beulah Koale) and Tani's (Meaghan Rath) budding relationship or reevaluating Adam's (Ian Anthony Dale) allegiances Five-0 continues to protect their loved ones and Hawaii's citizens and visitors in the 50th state.
