When alien microbes threaten the sun, an elementary school science teacher (Ryan Gosling) is dispatched to a distant star to find a way to avert doom. With his memory jumbled, he despairs his situation—until the arrival of another spacecraft presents him with an unexpected companion. Combining hard science with thrilling action and laugh-out-loud humor, this adaptation of Andy Weir’s (The Martian) novel is an exhilarating space adventure with a big heart.
