According to 
Blindspot wiki: Blindspot is an American drama series starring 
Jaimie Alexander and 
Sullivan Stapleton. The series was ordered by NBC on May 1, 2015 and premiered upon September 21, 2015. The actual series focuses on a mysterious tattooed lady who has lost her memory and does not understand her own identity. The FBI discovers that every tattoo contains a clue to a crime they are going to have to solve.
Blind spot gets right to the idea in the first couple of minutes - introducing all of us to our mysterious, tattoo-covered Jane Doe (Jaimie Alexander) emerging from a duffel bag in the 
Times Square. She has no idea who she is or even how she ended up naked inside of a bit of luggage. She may not remember her title, or anything else about herself, but all of us learn that she’s still in there someplace. Her likes, dislikes, abilities, and information are still present and predetermined; she simply has to uncover them. Kind of like when the girl decides tea tastes like blades associated with grass or starts randomly speaking China's (specifically Wenzhouhua).
