Someone from her past comes back into her life reviving an old friendship that unwittingly makes Kallie a target of a crazed gunman.

Meanwhile, distracted by studying the effects of a magnetic field to fold dimensions, Harlan Edmondson receives a surprise visitor. Mason is a man with a reputation for cold-blooded murder and he, too, wants answers to questions of time travel.

Behind the seemingly innocuous façade of a doctor and fellow scientist, Mason approaches Edmundson to seek explanations for the events that occurred over fifty years earlier that resulted in the birth of his son. Edmondson becomes an unwilling time travel guide when the secrets of the past meet with his future to reveal a convoluted temporal loop.
