A mission goes dangerously sideways when Will (ROBIN DUNNE) slips up, putting his Sanctuary teammates in jeopardy. Still reeling and traumatized from the events in Mumbai, Will is unfocused and struggles with memory loss, unable to recall anything that happened during his near-death experience. Suffering from insomnia, Will concedes to one of Bigfoot's (CHRISTOPHER HEYERDAHL) concoctions to help him rest -- and it works like a charm. But while in a very deep sleep, he receives two mysterious and unwanted visitors. Unsure of who the intruders are, or where they came from, Magnus (AMANDA TAPPING) is certain they were after something Will has...or knows. As they continue to try to unlock Will's memory, flashes begin to come back to him -- and what he starts to recall stuns the team, and sets them all on an entirely new path.
