Single-male-driven action adventure (as in "solo," not "romantically unattached"). Typically procedural. This can take the form of spies, police, investigators, whatever. If the person is running or hiding from a much larger organization, or has some deep personal mystery to address, so much the better.

I grew up with shows like that, but the closest I've seen in recent years was "The Player" on NBC (gone too soon, RIP) and "Shadow" on Netflix. Before that, the first seasons of "Human Target" and "The Transporter" really nailed that vibe.
