Devoted astronomer Dr. Ellie Arroway undertakes an emotional and spiritual journey after receiving the message she's waited for all her life--a mysterious signal beamed in from alien beings, who pass along instructions for building and piloting a craft that will presumably survive the passage from Earth to their home. While struggling to fund her mission, Arroway also struggles with her feelings about the nature of things, particularly after meeting a charismatic New Age believer who questions her disbelief in God. A deliberately-paced, meditative adaptation of the eponymous novel by Ann Druyan and "pop" astronomer Carl Sagan, who died during production.
