An apple a day might keep the doctor away but many of the inhabitants of Wenatchee in America prefer a Prozac a day to keep them happy and healthy. This documentary takes a look at the most prescribed anti-depressant drug in America by visiting Wenatchee - or "Happy Valley, Prozac Capital of the World" as it is known. Wenatchee psychologist Dr Jim Goodwin prescribes Prozac for all his clients because he believes everyone is depressed, they just don't realise it. He argues that Prozac is "probably less toxic than salt" - he even takes it himself. Not surprisingly he has his critics. Psychiatrist Dr Peter Breggin puts forward his theory that suffering is a necessary fact of life, while members of the Prozac Survivors Support Group give some harrowing accounts of how their lives have been destroyed by the drug.
