The siblings have survived countless dangers together, but this mission pushes them beyond anything they have faced before. Military forces guard their target with deadly precision.

Amy and Dan face an impossible decision that tears at the heart of their partnership. They can pursue the Clue that brings them closer to victory, or they can fight their way back to each other.
