Bob Bloomfield is, in the words of his best friend's wife, a 'selfish, arrogant a*sehole', who hasn't spent a great deal of time making friends in his 49 years on earth.

But what if he could change? What if Bob could stop the very thing that has made him the man he is, the death of his younger brother, Tom in 1986.

If he could save Tom, could he save himself?

. . . And what if all it took was a phone call - to his childhood self?
