Numb3rs is a crime procedural drama, that aired on CBS from 2005 to 2010 (six seasons) about an FBI agent and his brother a gifted mathmetician consultant, and how they learn to become friends through the solving of various different types of crime. It focuses on the Eppes family, a group of FBI agents and CalSci professors.
Each episode follows a different type of case from kidnapping, robbery, potential terrorism, domestic violence- to name a few- with personal drama between the brothers and the other people in life, like lovers, girlfriends, their father, their co-workers etc. It was praised by critics for being a character-driven show, creating attachment between the viewers at home and even the supporting cast. This created certain shows focusing on larger plot arcs on those supporting cast like their career development and personal events.
The hook of the show is how Charlie Eppes, mathematician "sees" the world through numbers and uses metaphors and similies to bring his understanding to the viewer and his FBI counterparts. The graphics during the show emphasize this point, often superimposing Charlie onto a graph-paper background with his equations and different types of graphs written out as he explains them in laments terms that has everyone going "Ah... Okay." Or making good-natured jokes about how his though process is far above their own mortal heads.
