In season one, Roy and Moss toil in the squalid basement of a huge company, fielding IT help-desk calls. Roy has a lousy attitude coupled with an eye for the ladies, while Moss is dressed by his mother and has an aerosol can of water clipped to his belt with which to spray his ear when it gets hot. Into their life of users, pizza, science fiction and firewalls comes middle manager Jen, a punky can-do career gal who doesn't know one end of laptop from the other.
