The story of Professor Stephen Hawking's early years. It is 1963, and our young cosmologist celebrates his 21st birthday. At the party is a new friend, Jane Wilde - there is a strong attraction between the two. Jane is intrigued by Stephen's talk of stars and the Universe. But she realises that there is something very wrong when Stephen suddenly finds that he is unable to stand up.
