A secret agent (Claudia Hiersche) comes out of retirement to stop a gun trafficker.

Nina Wenzel was the Superwoman of the Secret Service, a martial arts expert and explosives specialist. Five years ago, she helped bring down notorious arms dealer Geiger. But after a tragic accident left her niece and her two nephews orphans, she became a full-time mom. Just as Geiger is set to go on trial, he makes a spectacular escape. Only "Kung-Fu Mom" can catch him. Nina agrees to help, but only if she can take care of the kids in the evening. She soon finds Geiger, and the real ass-kicking begins when she's forced to join him in stealing a new super-bomb. Though the kids can't imagine what their boring Aunt Nina does all day, that soon changes when they're taken hostage. At the Secret Service headquarters, Nina is bound with explosives that will go off if the government doesn't pay 100 million Euros. Of course, they won't, so it's up to her new boyfriend to defuse the bomb. The rest is child's play, with Nina saving the world - before dinnertime.
