It's time to meet Mama McGarrett!

The first trailer for the new season of Hawaii Five-0 features the long-awaited introduction of Doris McGarrett (Christine Lahti), who was otherwise known as the mysterious "Shelburne" last season. Now that she's back in Steve's (Alex O'Loughlin) life, Wo Fat (Mark Dacascos) will stop at nothing to get to her.
