Firek Plinn was a Retellian man that owned a cargo ship with his brother, Firek Goff. In 2152, they attacked a Kriosian transport and kidnapped First Monarch Kaitaama with the intent to hold her for ransom. After the kidnapping attempt, their ship's life support systems were in need of repairs. Enterprise NX-01 offered assistance with the repairs, and Trip Tucker transported to their ship. Plinn and his brother boarded the Enterprise and had a meal with Captain Archer. Tucker and Kaitaama were rescued after they had escaped from Goff and knocked him out. (ENT: "Precious Cargo")
