To impress the popular girls on a high school trip to London, klutzy Callie buys real Prada heels. But trying them on, she trips -- conks her head -- and wakes up in the year 1815! There Callie meets Emily, who takes her in, mistaking her for a long-lost friend. As she spends time with Emily's family, Callie warms to them -- particularly to Emily's cousin Alex, a hottie and a duke, if a tad arrogant. But can Callie save Emily from a dire engagement, and win Alex's heart, before her time in the past is up?
