While investigating a young woman's death in her apartment, Ryan and Alexx try out a new technique for recovering prints off the victim before moving her. However, a fire breaks out in the apartment, which spreads over to the victim. Ryan tries to find a fire extinguisher, but finds a meth lab in the apartment instead. Ryan believes it was his tent (for the technique) that started the fire, but Calleigh, Eric and Natalia find out that the fire was a ticking time-bomb because the electricity in the room wasn't able to turn itself off, leading to a fire.
