“Prime Target,” an eight-episode thriller premiering Wednesday on Apple TV+, has the juicy vibe of a novel you might pick up at an airport and rip through in a single flight. It has an outlandish premise, beautiful people, and it ends on a cliffhanger every episode.

Leo Woodall stars in a mystery series as a young Cambridge scholar whose theories about prime numbers lead him into a web of international intrigue.
