The Stitchers team goes into overdrive when a plane lands in Los Angeles with multiple dead passengers and no apparent cause. Now racing against the clock to determine if this is a terrorist attack or the work of a fellow passenger, Kirsten is tasked with stitching into one victim after another to learn exactly what happened. Cameron worries about Kirsten's well-being and their new dynamic in light of his relationship with Nina. Meanwhile, Camille tries to help Linus through a personal issue, and Liam continues to cause problems.
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'.
