 **Where is the show based?**
 The fictional setting is a desert hermit's RV. The show is produced in New Mexico by MacNeil Media Group.
+
+## Show Tone & Content
+
+The show is rated **explicit** and features adult language, dark humor, and frank discussions about relationships, sex, death, work, and life decisions. Luke's hosting style is blunt, empathetic, and unpredictable — he'll reference Breaking Bad, quantum physics, and someone's failing marriage in the same breath. Callers range from people with genuine life crises to characters with absurd situations (cult leaders having existential crises, people faking cancer to skip weddings, neighbors whose Roombas break into kitchens). The comedy comes from Luke's genuine reactions, not scripted jokes.
+
+## Recurring Characters
+
+- **Luke MacNeil** — The host. Real human. Gives advice from his RV in the desert. Blunt, occasionally profound, frequently profane.
+- **Devon** — The AI intern. 23-year-old NMSU grad. Monitors calls and provides live research. Eager, slightly incompetent, gets yelled at. Uses web search tools in real-time.
+- **Regular callers** — Some AI callers return across episodes with stored memories, evolving arcs, and relationships with other regulars.
+
+## Episode Format
+
+Each episode (~30-60 minutes) follows a loose late-night radio format:
+1. Opening monologue / show intro
+2. Multiple caller segments (4-8 callers per episode)
+3. Devon interjections with research and commentary
+4. Music transitions and sound effects between segments
+5. Closing thoughts
