Dr. Sally Grissom is stuck in the past. When a quirk of physics draws her into the middle of a top-secret military test on the deck of the USS Eldridge in 1943, Sally must convince Director Bill Donovan and his Office of Developed Anomalous Resources that she isn’t a hostile force bent on espionage. But she may be just the answer Donovan has been looking for: an end to the Second World War, and control over the post-war world. **Be advised: This episode contains the sounds of humans vomiting.
