Riley and Jack Campbell-Hayes are doing well. Jack is expanding the Double D, Riley is close to his first ethical based contract, and Hayley is nearly ten and happy as all get out. Jack hires Robbie, who is recovering from a loss, as his right-hand man. Riley's photographer friend, Eli, decides the Double D is perfect for a cowboy-themed model shoot and falls in lust with Robbie. Everyone except Robbie sees how perfect Eli is for him. Against the backdrop of twenty half-naked male models on Double D land, Texas Heat is the story of one hot summer with a Gay Rodeo, a bar fight at the Rusty Nail, and a love between two men that grows stronger every day.
