An alien vessel at first crosses the bows of Enterprise, but refuses to return Archer’s hails. When it shows up a second time, it attacks and disables most of Enterprise’s systems. It does show up a third time, only to learn that Malcolm Reed and his team have substantially upgraded their armory. Captain Archer, who had been about to return to Earth for better weapons, is pleased to see that Enterprise can help themselves.
