Alicia Vikander gives a jaw-dropping performance that will keep you guessing until the very end in "Ex Machina." She plays a robot named Ava who was created by a narcissistic CEO who recruits one of his programmers, Caleb, to prove his creation is capable of independent thought. The more time Caleb spends with Ava, the more enamoured with her he becomes. The two soon hatch a plan that will allow her to escape the confines of the CEO's remote home, but it becomes increasingly unclear whether or not Ava is truly interested in Caleb or if she's simply manipulating him for her own gain.
