Once upon a time, mild mannered colombian father and chemistry teacher, Walter Bianco, was struggling. He had just learnt that he had developed a case of incurable lung cancer. What with the lowly salary of a highschool teacher, the medical bills and another baby on the way, Walter wasn't  sure how his family would cope. So, taking his fate in his own hands, he joined up with a mouthy former student and started making meth. That is the plot of the astoundingly 'original' and 'new' colombian show, Metástasis. Sound familiar?
