Join cousins Patrick and Beth in 1861 as they ride The Lincoln Special, a train carrying President-elect Abraham Lincoln to northern New York. Mr. Lincoln is troubled because Southern states are in an uproar over slavery. But Patrick and Beth care about one slave in particular a runaway named Sally who is hiding on the train. When a slave catcher finds out about Sally’s escape plans, the cousins must help her find a new route to Canada. They become “conductors” on the Underground Railroad. Meanwhile, Mrs. Lincoln and her son Willie join in. But will that be enough to keep Sally away from a slave catcher hot on her trail?
