Björn has been given an ultimatum: repair his work-life balance, or his wife Katharina will leave him - and take their daughter.

He reluctantly starts a mindfulness class and to his surprise, it's a revelation. He becomes calmer, more focused, and he's starting to understand what's really important in life. So when his client and brutal crime boss Dragan Sergowicz tries to interfere with his precious family time, Björn remembers his new-found goal to find serenity - and kills him.

Now Björn can deepen his practice and seek inner peace - violently.
