Superman travels to Spain to visit his family. What he doesn't know is that his dad, John McClaine, was a spy, and he's about to get wrapped up in spy bullshit.
Major Spoiler here: John McClaine is in the first 15 minutes and that's it.
Superman spends the rest of the movie playing cat and mouse with Ripley.
The writing here is terrible. The acting is meh.
Skip it.
