A girl signs up for a class. A couple hires an accountant. A group of co-workers decides to pool their money and buy a couple of lottery tickets. In the beginning, they're full of hope and optimism — and then something turns. Stories of good ideas gone bad. Prologue: Paul was a cop. One night he was pulling second shift when he had a perfectly good idea: He'd stretch out in the back seat and take a little nap during his break. He fell right asleep, and slept well until he woke up and realized the funny thing about the back seats of cop cars: The doors don't open from the inside. Paul is author of the book Bad Cop: New York's Least Likely Police Officer Tells All. (8 minutes) Act One: It was two months into the tour. Katie Else and the rest of the Riverdance cast had been performing eight shows a week. They decided to pool their money for the Mega-Millions lottery. Lotto fever gripped the cast. They started to genuinely believe they would take home about $2 million each, and quit Riverdance the next day. They took the stage the night of the drawing and pulled off their best performance ever, "For the Lotto!," trying to direct their energy towards the win. An hour later, at the hotel bar, the numbers came in. (17 minutes) Act Two: After years of neglecting their personal finances, Joel and his wife finally decide to sort things out. They hire a tax accountant named Len, whose casual manner is a real comfort, at first. But then, "casual" turns into "drunk" and then it's clear that he's just plain delinquent. Joel tries to take his business elsewhere, but Len refuses to let go of their file. He begs for a second chance, which it seems, came too late. Joel Lovell is executive editor at Pineapple Street Media. (8 minutes) Act Three: Davy Rothbart was on a 136-city tour appearing on morning TV talk shows to promote his book Found: The Best Lost, Tossed, and Forgotten Items from Around the World. Just before one appearance he had what seemed like a great idea at the time. Without letting the host know, he tested it out, live, on-air. Davy is the creator of Found Magazine and author of the book of essays My Heart Is An Idiot. (6 minutes) Act Four: When Elspeth was a girl, she wanted nothing more than her father's attention. He was busy, a doctor, and distant. One day he agrees to put on a volunteer seminar for their church, about his area of expertise: "The Function of the Heart." Elspeth and her best friend are the only two kids who show up, and Elspeth is attentive and engaged, the perfect student. It was an incredible experience for her, the best day she's ever spent with her dad...she thinks. That is, until her mother takes her aside and explains her big mistake. (8 minutes)
