n. a person or thing that shows marked ability or excellence.
The Knoxgold mining company has cheated Joe McDonald and his crew out of their hard-earned bonus, and there’s nothing that they can do about it — until they discover an unknown gold-vein deep inside the mine. Together, they devise a plan to get it past security.
