What if you could live forever?

A man travels through time in an epic struggle to save the woman he loves and to understand the mysteries of life in this sci-fi drama. In three parallel stories spanning a millennium, Tom (Hugh Jackman) searches for a legendary tree believed to grant eternal life in 16th-century Spain; tries to discover a cure for his wife's (Rachel Weisz) cancer as a present-day scientist; and traverses the universe as a 26th-century astronaut.
