Criminal Minds: Beyond Borders Episode 1.01 The Harmful One

Unit Chief Jack Garrett (Gary Sinise) and his International Response Team (IRT), comprised of military hero and profiler Matt Simmons (Daniel Henney), brilliant tech analyst Russ "Monty" Montgomery (Tyler James Williams) and fearless medical examiner Mae Jarvis (Annie Funke), are a specialized Division of the FBI tasked with solving crimes and coming to the rescue of Americans who find themselves in danger while abroad.

In the series premiere, Garrett and his unit travel to Thailand when three American volunteers go missing during a trek to Bangkok. Once there, former colleague Clara Seger (Alana De La Garza), a cultural anthropologist, helps them rush to gather evidence leading to the UnSub before a storm threatens to wash it away.
