In “Pria”, the crew of The Orville receive a distress call from a mining vessel that is stuck on a comet caught in the orbit of a star. After Ed Mercer and his crew save the captain of the mining vessel, a woman named Pria (guest star Charlize Theron), they welcome her on board with open arms. The welcome is a little too open for first officer Kelly Grayson, who soon begins to question Pria’s intentions.
