When a thief is found dead in a pottery shop near an open safe, the CSI team investigates the case. They find several prints and soon they learn that the man entered through the back door and was hit by a ceramic garden gnome on the head. Among the prints, they find one from the missing case of a four year-old girl, Melissa Marlowe, which happened twenty-one years ago. They summon their parents and using her photography when she was a child and a software, they learn that Melissa is Tammy Felton, the daughter of the dead robber. Meanwhile, Sara and Warrick investigate the case of an old woman burnt to ashes in her rocking chair and Sara believes it is a case of spontaneous combustion since no fire accelerant was found, but Warrick disagrees.
