The BAU team will hit the streets of Las Vegas when "Criminal Minds" returns with another all-new episode on CBS this Wednesday.

In the last episode, "Gabby," the BAU team worked quickly to rescue a 4-year-old girl who was kidnapped in Mississippi. The episode featured "The Bold and the Beautiful" actress Ashley Jones who guest starred as Kate Hoffer, the missing girl's mother. Other guest stars included Sianoa Smit-McPhee as Sue Walsh, Julia Butters playing Gabby Hoffer and Molly Culver as SSA Tia Canning, reports Hollywood Hills.

CBS released a teaser video for the upcoming episode, titled "Persuasion," which gives insight about the Las Vegas underworld where hundreds of people live in tunnels underground.

According to Broadway World, the official synopsis states: "Mysterious drowning deaths discovered in the Las Vegas desert have the BAU trying to figure out the true cause and motive for the murders."
