Garth Mathers is a paranormal police consultant for the Anchorage Police Department, termed a 'ghost whisperer'. He has solved countless cases with his trusty spectral sidekick, Bernie, who may or may not be an alcoholic.

They travel to Santa Barbara to participate on the "Cutting Edge Consultants" panel hosted by Professor Stein (Bill Marchant), but when there is a murder, they help Shawn and Gus on the case.
