Swedish billionaire Olaf Gedda is found dead and his eccentric fishing colleague, Gotilda Salamander, is arrested for firing the fatal shot. Her prints were found all over the bucket of worms beside the body, so who else could it be? Salamander's old flame, investigative journalist Jerker Rhindtwist, discovers that a few others had motives as well but, in the end, Salamander must escape from jail and, using her computer hacking expertise, hook the murderer herself. With the help of solid research on Rhindtwist's part, and well-planted karate kicks on Salamander's, the efficient duo finds its way to justice, Swedish style.
