Devastated by the loss of her parents at the tender age of eight, Ellie (
Jodie Foster) yearns for contact with extraterrestrials, but shies away from contact with anyone on earth. Having been hurt by feeling, she relies entirely on science, on what can be proven. After a one-night-stand with Palmer Joss (
Matthew McConaughey), a charismatic divinity school drop-out, she leaves, to continue to listen for whispers from the universe, despite short-sighted bureaucrats who cut her funding. When she finally hears something, the government steps in. The message is to build a machine, apparently to be used to go to the source of the message. Joss turns up as an advisor to the President who is assigned to the panel that will select the person who will make the trip. He does not believe that Earth should be represented by an atheist. And he does not want to lose Ellie again. Ultimately, she does make the trip, and finds that she is profoundly changed by it. She finds herself asking others to believe what she says without evidence, on the basis of faith.
