The trailer shows how Lionel Essrog (Norton) became a private detective with the help of Frank Minna (Willis). When his mentor is murdered, Lionel sets out to find out who killed him and to "make 'em regret it."

"There's something going down, and it's big," Lionel says in the trailer. "And they were not happy about what he found."
