Part 1

"Dear Harry,
I'm not sure how to explain this easily..."

~~~~~

Sarah is hopelessly in love with world-famous Harry Styles, but she's a huge Larry shipper and believes he belongs with Louis. All she wants is to help Harry, so by leaving him a letter written at an impossible date she attempts to free him from what ties him down in present time. Traveling through time using a certain red phone booth, she discovers that there may be a way for her to meet her idol in the future. However, when she slips up and accidentally erases her favorite band from history, she must go back in time again and fix things before they become irreversible.

When you mess with one aspect of time, you mess with all of it.
