Shanna was a librarian that loved her job and the small town she lived in. What she loved most about her life, though, was her cat, Fritz. Fritz would lie around the house sunbathing while Shanna was at work, or so she thought. Fritz was actually a cat with superpowers and he went around saving people all day long. 
Even while saving countless others, Fritz would inconspicuously save Shanna, too, whenever she would have accidents. Sometimes Fritz felt like that alone was a full-time job. 

Since Fritz would do this all day, he got the attention of Drakken, a huge Rottweiler living in the same neighborhood who didn't seem to care for the attention Fritz was getting from everyone, including his family. Drakken knew he had to put a stop to Fritz's heroic activities. He devised a plan to take down Fritz and recruited a few other dogs in the process.
 
Tensions grew heated as Drakken and his cohorts did everything in their power to sabotage Fritz time and time again. Finally, Fritz caught on and tempers quickly erupted. A huge fight broke out which ultimately ended with the defeat of Drakken. Afterward, Fritz realized that inside this mean, ferocious dog was an insecure puppy that just wanted attention and love. 

Fritz took mercy on Drakken and helped him to see things in a different light. Drakken then trotted off to spend time with his family and everything returned to normal.
