9-1-1: Nashville is leaning into the chaos by having Chris O'Donnell reveal on the show that LeAnn Rimes' onscreen stripper son is his secret child. The official trailer, which ABC released on Thursday, September 25, introduces Us to O'Donnell's Captain Don Hart, who is a veteran firefighter and former rodeo rider. His team of emergency responders includes his son, Ryan Hart (Michael Provost). But elsewhere in the city of Nashville is a stripper named Blue Bennings (Hunter McVey), who is only a firefighter while dressed up for his shift dancing at the local bar.
