Aryn wakes up every morning and gets ready for her brother's 18th birthday. She makes a cake, wraps the present, and sets everything up for his arrival. She lives a normal teenage life. Turns out, she lives the same day over and over again, because of a severe brain condition. Her family keeps it the same day by resetting everything done when she sleeps. They make sure her schedule remains the same and no one tells her the date. Everything is good until she goes somewhere not on schedule. You think this wouldn't change anything, but when a guy she meets falls for her, he has to make sure that she falls in love with him. Over and over and over again.
