"What About Bob?" is a comedy film that follows the story of Bob Wiley, a neurotic man with various phobias. He seeks help from his psychiatrist, Dr. Leo Marvin, who is about to go on vacation. Bob's desperate need for support leads him to follow Dr. Marvin to his lakeside retreat, where his antics disrupt the doctor's plans and life.
As Bob ingratiates himself with Dr. Marvin's family, he begins to make progress in overcoming his fears. The film humorously explores themes of therapy, personal growth, and the unexpected bonds that can form between people, even in the most chaotic situations.
