Star Trek: Enterprise: Season 2, Episode 3
When attempting to explore a new planet, Enterprise triggers a cloaked mine. While the crew deal with the resulting damage, it's discovered another mine is stuck to the hull. During Reed's attempt to disarm it, a spike is driven into his leg, trapping him out there. While Archer goes out on the hull to help him, the rest of the crew learn they are in a minefield belonging to the Romulan Star Empire, who demand Enterprise leave or face destruction.
