Lazy cops in a neighboring precinct think they have stuck the 15th's detectives with an impossible case, but some details lead to a suspect, who fires some shots at Andy. Andy is unhurt but freezes, and worries about his approach on the job. Andy and an also-portly Greg decide to have a weight-loss competition. Greg also befriends an attractive officer named Abby while trying to work out on some confiscated stair climbers.
