A smooth-talking smuggler delivers three remarkable women to lonely miners, and Kirk learns the secret of their allure.
The Enterprise chases a small ship into an asteroid belt and rescues its captain, the con man Harcourt Fenton Mudd, along with three strikingly beautiful women he is taking to become wives for settlers. The chase burns out the starship's power crystals, and Kirk has to bargain for replacements with lonely miners on Rigel XII.
The women's beauty turns out to depend on an illegal Venus drug, and without it they look ordinary. One of them, Eve, learns that her confidence matters more than the drug. Roger C. Carmel played Mudd, who returned in I, Mudd and in the animated Mudd's Passion.
