The series focused on the problems and events that had led Bonaduce, speaking retrospectively, to consider his life a "car crash". Over the course of filming, Bonaduce's previously publicized abuse of drugs resumes; an initially successful effort to replace that unhealthy behavior with overzealous exercise/bodybuilding backfires (as he falls into experimenting with performance-enhancing drugs, in order to "chase" the endorphin "rush" that overexercising gives him); and, later attempts suicide. He also makes periodic attempts to save his crumbling marriage by attending couple's counseling with his wife, Gretchen (who, over the course of the series, evolves from being Danny's constant enabler/excuse-maker, to filing for divorce after Bonaduce's dangerous antics finally push her too far).
