When young seamstress May Bedloe is left alone and penniless on the shore of the Ohio, she finds work on the famous floating theatre that plies its trade along the river.

For the sake of a debt that must be repaid, May is compelled to transport secret passengers, under cover of darkness, across the river and on, along the underground railroad.
