In Dublin, Ireland, 1746, Maddie falls in love with a shapeshifer named Conor. Before they can carry out their plan to run away and marry, fate intervenes, leaving Conor murdered and Maddie dead by her own hand. Their souls are cursed for eternity - with a twist. Conor will have three chances to undo the damage that was done and save them both.

At the turn of each century, on the anniversary of their deaths, Conor will take on his wolf form with one quest in mind - find Maddie and convince her to believe in him once again, wherever she is and whoever she has become.
