After a doctor flatlines at the hospital, Terry and Sharon Stone tackle a medical murder mystery where they must question staff and sew up loose ends.

Detective Terry Seattle (Will Arnett) is back and this time, the case is critical. Along with his two celebrity guest stars, Jason Bateman and Maya Rudolph, he is on a mission to figure out... who killed Santa? But here's the catch: Jason Bateman and Maya Rudolph aren't being given the script. They have no idea what's about to happen to them. Together, with Terry Seattle (and many surprises), they will have to improvise their way through the case... but it will be up to both of them to name the killer.
