Jesse L. Martinis back in action!
PEOPLE has the exclusive first trailer forThe Irrational, an upcoming investigative drama seriesarriving this fall that promises lots of action and peculiar mystery-solving.
Martin, 54, plays distinguished behavioral science professor Alec Mercer, who is called upon to use his expert knowledge to work out puzzling mysteries in high-stake cases linked to governments, law enforcement and corporations.
“I was brought in because I know people and why they do inexplicable things,” Mercer explains in the trailer, before listing “bereavement sex” and “attentional blindness” among the unique cases he covers.

Mercer uses his keen insight and depth in understanding of human behavior to lead a team along with him in getting closer to solving each illogical case throughout the series.
“People are irrational, but predictably so,” the professor says. “One error of judgment leads to another."

Martin recently portrayed detective Joe West for eight seasons of The CW’sThe Flash, whichwrapped in May.
Before that, he earned his investigative cred on nine seasons ofLaw & Order, then dipped back into the world of notorious crimes last August as host of HLN’sHow It Really Happened with Jesse. L Martin.
“My agents, managers came to me and said, ‘Here’s an interesting project,'” Martintold PEOPLElast year. “And I never thought of myself as a host, really, of anything. I rather enjoy being able to hide myself in a character. But this was such a cool project. It became a great, great gig for me.”
