It's been one month and fourteen days since she left. Jacob (Sam Heughan) is a writer and Cassandra (Arabella Oz) was his muse. His reason for writing. His reason for loving. She will forever be the one who haunts him every time he sits at his keyboard trying to write and rewrite their story. And each time, as Jacob tries to figure out why he lost the love of his life, he relives every moment, both real and imagined, searching whether he made the right decisions and determined to write the perfect ending for them. For her.
