Let No Man Tear Asunder - S3.E9

An autopsy reveals a murdered woman's heart has been surgically removed, prompting Nick and Tracy to investigate the black market for human organs. Working undercover, Tracy visits a suspected dealer at the local hospital, unaware that Natalie Lambert is scheduled for a routine knee operation at the same facility. Upon learning Natalie has been chosen as the next "donor," Tracy is overcome by the dealer and prepped for the operation instead.
