Sometimes the past is better left alone.

Kaley Kline is thrilled to have landed a job as director of the new Tesla Museum in Colorado Springs. To make the museum successful, she searches for undiscovered works to display. When she finds an old safe that might have been Tesla's, she's shocked to find some diary pages supposedly written by the inventor himself. 

Kaley initially thinks either that the journal is a fraud or Tesla was experiencing a nervous breakdown when he wrote it. However, if his experiments were real, the world will never be the same. She decides to secretly build Tesla's time machine and attempt to go back into her own life to change a decision she has always regretted. 

She prepares for a trip to the past, not knowing whether she will electrocute herself or travel back to the Boulder of her sophomore year in college. But an old boyfriend might have hidden some secrets from her—secrets that could have her fighting for her life.
