ON "PRIMETIME: WHAT WOULD YOU DO?," FRIDAY, MAY 21

Will parkgoers intervene when an out-of-control soccer coach pushes a young player beyond his limits? Will anyone actually help an inebriated woman start her car? Will fellow pharmacy customers come to the aid of an elderly woman who needs a prescription filled but can no longer afford it because insurance won't cover anymore? Using hidden cameras, "Primetime: What Would You Do?" sets up everyday scenarios and then captures people's reactions. Whether people are compelled to act or mind their own business, John Qui�ones reports on their split-second and often surprising decision-making process, on "Primetime: What Would You Do?," airing FRIDAY, MAY 21 (9:00-10:00 p.m., ET) on ABC.

This series shows what people actually do in the face of everyday dilemmas that test their character and values. Friday's scenarios include:

· BEATING THE BREATHALYZER: It's supposed to be a silver bullet in the war against drunk driving, the ignition interlock device, which prevents a car from starting until the driver proves he or she is sober by breathing into a tube. Breathalyzers have been installed in the cars of repeat DWI offenders throughout the United States. But for someone insisting on driving while drunk, there is a loophole - getting a sober friend, or even a stranger, to blow into the device. What would you do if a stranger begged you to beat the system by blowing into her car breathalyzer - enabling her to start her car? What if she's a mother with a newborn in the back?

· OUT-OF-CONTROL SOCCER COACH: Young athletes, driven by coaches to exhaustion, have collapsed in practice from heat stroke or cardiac arrest - and some have even died. It's a frightening scenario. So what do you do if you're out in the park on a hot summer day and see an angry coach pushing a young soccer player to the brink?

· SKYROCKETING PHARMACY COSTS: At a small pharmacy, the clerk behind the counter tells an elderly woman that the diabetes medication she desperately needs is no longer covered by her insurance. Unable to afford the $150 pills, the woman dissolves in tears, pleading with him that she lives on social security. What will bystanders do? And what if the needy customer isn't elderly - but a young woman out of work?

"Primetime: What Would You Do?" has won awards from the Chicago International Television Festival, and the Avon Foundation's 2006 Voice of Change award for exposing "injustice and wrongdoing against women and bringing the message of domestic violence to the mainstream." The Columbia Journalism Review has called the program "a Candid Camera of Ethics."
