She's lived many lives, but her goal is always the same: survival.

ER Doctor Dev Balakrishnan is late for work when he sees her: slumped on the curb like a broken doll, covered in blood.

Everyone else walks on by. Not Dev.

He saves people's lives every day, but Brooke is different: prey one minute, predator the next. As she spins her web of stories Dev finds himself hopelessly caught up in her world of danger and deceit.

Brooke will test Dev in ways he never dreamed of.

Whether he passes or fails will become a matter of life and death - for both of them.
