The Irrational season 2: next episode, cast, plot and everything we know
Jesse L. Martin returns as a brilliant professor with a knack for getting inside peoples' heads.
Following the success of The Irrational season 1, NBC quickly ordered up another season of the crime drama that centers on Professor Alec Mercer (Jesse L. Martin), behavioral scientist and leading expert on human behavior based on the book Predictably Irrational by Dan Ariely.
While the 2024 fall television landscape is once again peppered with procedurals, The Irrational season 2 is set to offer a sexy, fresh twist on the genre. Watching Professor Mercer solving crimes is just as enjoyable as watching him navigate his personal life. Mercer is the guy the police and governmental agencies call when they're trying to figure out the "why" as much as the "how" of a crime; through behavioral analysis, Mercer and his team are always able to provide key insight into the toughest of cases.
