In 1944, young Leon Zgierski (Roman Danylo), an inmate in the Birkenau concentration camp watches as First Lieutenant Karl Rademacher shoots his wife and sends his daughter to the gas chambers. The murder is witnessed by a mysterious figure, time-traveler Nicholas Prentice (Alex Daikun), who grabs Radermacher's SS jacket and, after eluding guards, pulls out an antique watch and vanishes into a glowing orange circle. We then flash forward to the present where Leon is an old man (Peter Boretski) and his son by a second marriage, Aaron (Saul Rubinek), is a lawyer who has made it his life's work to track down Rademacher. Aaron believes he has found the war criminal living in Philadelphia as Robert Greene (Jan Rubes) but he can't muster enough evidence to convince his ex-wife, U.S. Attorney Gwen Sawyer (Lindsay Crouse), to bring charges against the old man. That is, until he gets help from the time-traveler, who offers the jacket and presumably enough documentation
