A wise old dog travels through the centuries in search of the master who granted him immortality.

A winter's night, Venice, 1815.

A 217-year-old-dog is searching for his lost master.

So begins the journey of Tomorrow, a dog who must travel through the gilded courts of kings and the brutal battlefields of Europe in search of the man who granted him immortality.

But Tomorrow's journey is also a race against time. Danger stalks his path, and in the shadows lurks an old enemy. Before his pursuer can reach him, he must find his master - or lose him forever.

Tomorrow is a spellbinding story of courage and devotion, of humanity across the ages, and the unbreakable bond between two souls.
