I uploaded the new promotional stills from the episode 1×06: The Godfriender of Making History and read below the official synopsis:
Dan, Deb and Chris find themselves stuck in 1920s Chicago, with Al Capone (guest star Tim Robinson) holding their time travel bag hostage. Chris opts for a play-it-safe plan, using history to take out Capone, while Dan and Deb befriend him instead. As they teach him how to be a better mobster – and husband – they quickly realize that proving their loyalty may not be as easy as they thought in the all-new “The Godfriender” episode of MAKING HISTORY airing Sunday, April 23 (8:30-9:00 PM ET/PT) on FOX.
