Plot

In New York City, neurotic and multiphobic Bob Wiley spends his life in a near-constant state of distress. Exasperated by Bob's high-maintenance needs, his therapist closes his practice and refers Bob to the egotistical and controlling Dr. Leo Marvin, who believes his new self-help book, Baby Steps, will make him famous. Leo gives Bob a copy of Baby Steps and makes an appointment to see him in a month following the Marvin family's vacation. Unable to cope without regular reassurance, Bob repeatedly calls Leo's telephone exchange in failed attempts to deduce where he is staying. Bob then visits the exchange while posing as a detective investigating Bob's suicide and learns that the Marvins are at Lake Winnipesaukee, New Hampshire.
