Clark Kent's old high school flame, Lana Lang, is now a successful fashion designer. At a fashion show one night, reporters Clark and Lois spot her with Lex Luthor. While Lana goes in a dressing room to help one of the models, she's grabbed by two women - one a huge, manly-looking beast. Clark hears a scream, runs and changes into Superman and saves Lana as she is thrown through a high-rise window.
Lana knows Superman is Clark. She figured it out as soon as Superman began making headlines, the same time Clark left for Metropolis. She knew he had special powers when he was in Smallville. Superman doesn't deny it, surprisingly. He warns her that Luthor is a bad guy, but she doesn't believe it. She finds out, however, quickly and then decides she's going to be a spy and help and help find out about Luthor and a deal he is making with an arms dealer. This girl doesn't lack for self-confidence or modesty.
It turns out she isn't as smart as she thinks and Luthor is on to her....and Superman has to, once again, bail her out.
Overall, kind of lesser episode, especially coming off the intense two-parter on "The Main Man." This is a bit dull after those shows.
Also...how can Clark trust Lana to keep his famous secret? That problem is never addressed in this episode.
