What if your life had an ‘undo’ button?

Arlo Knott develops the mysterious ability to reverse his last action. It makes him better at life, able to charm any woman and impress any friend. He can experience anything without worrying about the consequences.

His is a life without without regret. By his very nature, he can’t lose.

But second chances aren’t all they’re cracked up to be.

As wonderful as his new life is, a mistake in Arlo’s traumatic childhood still haunts him and the temptation to undo, undo and keep undoing could be too much to resist.
