After an action-packed first season that saw the first responders work together to uncover Ma Taehwa’s criminal past, a new partner from the National Forensic Service will join the team as they look to expose the real criminal mastermind in The First Responders season two, coming August 4 to Disney+.

An expert in medicine, law, engineering, firearms, hacking and toxicology, Dex has made a name for himself as a criminal architect responsible for some of the biggest scandals in Hollywood, politics and billionaire circles.

Determined to get revenge on Hogae, Dex will break his only rule and return to South Korea to carry out a crime himself in an attempt to takedown the first responders.
