He is the witness protection officer to the Canada-bound Falcone (now known as McDougal here in Canada) family. The Falcones consist of Jimmy, his wife Cookie, his kids Petey, Theresa, and Gina, and his uncle Cheech. Strait usually uses his horse, Horse, as a means of travel, but he also views horse as a great friend. He's been a witness protection officer to the Falcones since Jimmy threw the Don off the 19 floor suite. (The Falcones are a crime family y'know)
