Obsessed S02 E04 William & Nanci

Al and his two daughters, Tammy and Jodi, each suffer from agoraphobia. Al has been virtually homebound for 30 years. Tammy is afraid of leaving her 20-mile safe zone. And for Jodi, the problem is literally a matter of life and death--she can't go over a bridge she needs to cross to get desperately needed medical care for her son.
