 Meet Angela Fairbanks, she used to be CIA, but now she s found a better-paying career as a thief. There s been a break-in at the American consulate and secret plans to the Tower of London were taken. Pendleton suspects Fairbanks, but the only evidence they have are a few strands of hair found on the scene. Sam needs to sneak into Fairbanks  hotel and see if she can get some hair to match the DNA. DNA is better than a fingerprint for identifying people, it s in our cells, and can be found in blood, saliva and hair.
