Sadie may seem like the typical girl next door - except she isn't. At age eight, when she finds Mommy in the bathtub, floating in a pool of blood, Sadie becomes obsessed with murder. Sadie's Guide to Catching Killers is the prekill to Sadie the Sadist: X-tremely Black Humor/Horror, delving into Sadie's bizarre childhood to unravel what makes her the psycho we know and love.
Like many people, Sadie feels undervalued and frustrated. Employed by a supermarket, she plots to murder coworkers - or lure them into the employee bathroom for a quickie. Sick of being treated like a robot, she taps into a powerful (and deranged) alter-ego and transforms into Sadie the Sadist.
