You won’t believe what people do when they think no one’s watching! The hit hidden-camera series “What Would You Do?,” hosted by ABC News’ John Quiñones, returned to ABC for a historic 16th season on SUNDAY, FEB. 18 (10:01-11:00 p.m. EST) with episodes available the next day on Hulu. Quiñones welcomes guest correspondents Sara Haines, co-host of “The View,” and W. Kamau Bell, cultural commentator and television host, as they observe how real people react when tricky situations and moral dilemmas arise in public settings.

John Quiñones is the anchor of "What Would You Do?," one of the highest-rated newsmagazine franchises of recent years.  It's a hidden-camera show in which John and his team set up scenes of conflict and watch, with millions of others, while bystanders make the choice of what to do, if anything.    

We have all been there. You’re out shopping or taking a stroll in the park or about to order dinner at a restaurant, and suddenly, something disturbing happens right in front of you. And that little voice in the back of your head says, “Do Something!” Do you step in or step away? It's inspiring to see the good nature and sometimes heroism of people just going about their day. And sometimes, they just have fun with it.
