After being around for centuries and now living in the modern age, vampire Adam (Tom Hiddleston) is a rockstar who cannot grow accustomed to the new modern world with all of its new technology. While he lives in Detroit, his wife Eve (Tilda Swinton) lives in Tangier, flourishing in the new world. But when she senses Adam’s depression with society, she gets on a plane and goes to see him. Shortly after Eve gets there, her little sister, Ava (Mia Wasikowska), shows up after 87 years and disrupts the couple’s idyll reunion.
