In the 1930s, famous glassblower Ernst Muller perfected a secret technique to create a set of the most valuable marbles in the world. But as time rolled on and the dark clouds of world events prevailed, Ernst Mueller sadly lost his marbles. Flash forward to today. Meet FBI Agent Dana Dillion O'Toole, DD to her friends. DD loves rock and roll, fast cars and catching bad guys. But catching a good guy to love, just isn't working for DD. She's too quirky, and maybe too suspicious. One thing for sure, Agent O'Toole is one fiery, go-getter when it comes to solving a case. Problem is, DD runs too hot and fast which causes a few headaches for her nervous boss. It's time for Agent O'Toole to chill and take a break. So, DD gets assigned to an irrelevant, go-nowhere case. Her boss is convinced Agent O'Toole will stay out of controversy and off the media radar. A frustrated and unhappy DD takes the case only to find herself free falling into a dark rabbit hole filled with zany, crazy people who are all in search of Muller's Marbles.
