When an MI6 agent is found dead, Kirsten struggles to sort through his memories due to the visual codes that the spy used to keep secrets. Meanwhile, Linus and Camille go on a double date, but not with each other.
Kirsten is a young woman recruited into a covert government agency to be 'stitched' into the minds of the recently deceased, using their memories to investigate murders and decipher mysteries that otherwise would have gone to the grave.
Working alongside Kirsten is Cameron, a brilliant neuroscientist whose passion for the program is evident in his work. The secret program is headed by Maggie, a skilled veteran of covert operations, and includes Linus, a socially immature bioelectrical engineer and communications technician. Kirsten's roommate, Camille, a gifted computer science grad student, is also recruited to use her skills to assist Kirsten in her new role as a 'stitcher'.
