Arriving in Italy in 73 B.C., the pair discover that Spartacus is being sent to die in the arena in Rome, altering history and preventing him for leading the slave revolt in Capra. They are bought as slaves but when their escape attempt fails, they have to Omni out. That puts them in Hannibal Missouri in the 19th century, where they encountered Harriet Tubman. She is still a slave, having never formed the Underground Railroad. While Jeff and a young Sam Clemens try to free her, Bogg manages to ""purchase"" her in a poker game. With history back on track, it's back to Rome, where Bogg ends up fighting Spartacus in the arena. Jeff and his newfound friend Calpernia manage to steal a chariot belonging to her father Cicero, break out Bogg and Spartacus, and get history back on track. (thetvdb.com)
