The Theory of Everything tells the extraordinary story of the renowned astrophysicist Stephen Hawking and his relationship with fellow Cambridge student Jane Wilde. 

Once a healthy, active young man, Hawking received an earth-shattering diagnosis at the age of 21. With Jane fighting tirelessly by his side, Stephen embarks on his most ambitious scientific work, studying the very thing he now has precious little of - time. Together, they defy impossible odds, breaking new ground in medicine and science, and achieving more than they could ever have dreamed. 

The film is based on the memoir Travelling to Infinity: My Life with Stephen, by Jane Hawking.
