"Johansson plays an alien on earth, disguised as the perfect aesthetic form of a mesmerizing woman. She scours remote highways and desolate scenery looking to use her greatest weapon to snare human prey -- her voracious sexuality. She is deadly efficient, but over time becomes drawn to and changed by the complexity of life on earth. With this new found humanity and weakening alien resolve, she finds herself on a collision course with her own kind. Taking her point of view throughout, the film presents a unique look at our world through alien eyes."
