This week it’s murder on the Mexican border.
When two men are discovered with their right legs amputated, the scene is set for a bizarre and gruesome episode that requires every minute to reach its conclusion.
Only one of the men survived the attack, while the other can only remember odd details about how he came to lose his leg.
The team discovers that the suspect likely has some medical knowledge. So when a third amputation victim manages to make it to a hospital, the crew soon realises they are involved in a race against time.
