ON THE SEASON FINALE OF "PRIMETIME: WHAT WOULD YOU DO?"

What would you do if you saw an overweight woman being verbally harassed? Imagine seeing a purse snatcher in broad daylight -- would you be able to pick out the thief in a lineup? 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 the season finale of "Primetime: What Would You Do?," TUESDAY, MARCH 25 (10:02-11:00 p.m., ET) on ABC.

Tuesday's scenarios include:

� Overweight Harassment: An overweight person encounters a cruel group of teens who ridicule her while she's sitting on a public bench at a beach boardwalk. Will anyone walking by intervene?

� Eyewitness ID: When a lunchtime purse snatching happens in a split second at a crowded public square, many witnesses get a good look at the crime. But can they pick the real thief out of a lineup? Is there a difference when "Primetime" changes the race of the purse snatcher?

� Bridal Gown: At a wedding gown fitting, a bride-to-be reveals her choice to friends and family. But what if the gown is so ugly that her closest friends and family want to scream? Will they keep their thoughts to themselves or speak up honestly?

� Cheating Couples: "Primetime" continues the "cheating couples" scenario this week, when viewers see a best friend's husband getting way too cozy with another woman. But this time the stakes are higher. Will she tell her friend?

This week's interactive "What Would You Do" scenario segment incorporates viewers' reactions to a scenario about what they would do if faced with the option to buy a home next door to friends whose children you think would be a bad influence on your children.

According to a recent Columbia Journalism Review essay, "Primetime: What Would You Do?" is "the flip side of reality TV... rather than show how people act in manufactured situations when they know they are being watched, they show us how people act when they don't." The series 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 foundation called the program "an important work of journalism that illustrates the unwillingness of many people to become involved or speak out against domestic violence."
