A double homicide near the Florida Everglades, where the killer leaves a bizarre trademark, takes Manny and the BAU to South Florida at the request of the Miami-Dade Police Department. They arrive in Miami just in time to discover that the killer has struck again, and this time, his method of double-murder is even more mind boggling. The BAU goes to work, but Manny has a sense that things are going to be different, that this killer is different than any they've chased before, and he fears for his team. His suspicions prove to be fact as the unsub succeeds in killing a third time, affecting Manny's world in a profound way as he loses more than he imagined possible.
