In the summer of 1989 in Hiawatha, Wisconsin, college student Jimmy Foley can't move forward with his life until he finds who is behind his sister Bridget's hit-and-run death. Sketchy evidence points to the local cranberry kingpin, but no one in town has the power to take him down. When Jimmy brushes against a gravestone, he finds himself in Washington DC in 1862, where he comes across other time-traveling "stitchers" working to solve the murder of the British ambassador. The stitchers try to recruit Jimmy to help solve the murder, in an effort to prevent the reversal of the outcome of the Civil War. Jimmy agrees, and between helping the stitchers and investigating his sister's death he uncovers an even more diabolical human trafficking plot. In a wild time-jumping chase, Jimmy and the stitchers risk everything to stop the cranberry king from realizing his dystopian vision.
