The last year has been smooth sailing for Casey Donovan. She and her boyfriend Nate are doing better than ever, and things at home are good, too. Everything's been so calm, she hasn't "tripped" back to the nineteenth century in ages.
Then the unthinkable happens and she accidentally takes her rebellious brother Tim back in time. It's 1862 with the Civil War brewing, and for Tim this spells adventure and excitement. Finding himself stuck in the past, he enlists in the Union army, but it doesn't take long before he discovers real life war is no fun and games.
Casey and Nate race against the clock to find Tim, but the strain wears on their relationship. It doesn't help that the intriguing new boy next door has his sights on Casey, and isn't shy to let her know it.
Can Nate and Casey find Tim in time to save him? And is it too late to save their love?
