As a luxury cruise ship sinks, unlikely heroes come to the rescue. Rose-Marie Howe was shocked when her cruise was interrupted by a blackout. But she soon realized the loss of power was the least of her concerns. The ship was sinking, and no one seemed to know what to do. Moss Hills, a guitarist in the ship’s band, decided to go to the lounge to investigate. He found instruments thrown about the stage and realized he couldn’t hear the ship’s engines. He also couldn’t find the captain or any of the senior crew. This is the story of how a guitarist, a bass player and two magicians saved hundreds of lives. We also talk to marine historian Mallory Haas about what we can learn from disasters at sea.

A simple drive home becomes a life-or-death struggle. The weather wasn’t great, but Bryan Pederson was just a few blocks from home on a street he had driven a thousand times. Still, the wind was howling and rain was pouring down. Sitting at a traffic light, he heard a loud crack. Instantly, he was trapped in a car being crushed by a tree. Ten cars drove past the scene, peering through the rain at the crumpled SUV and the tree blocking the road. Nine of them turned around and drove away. This is the story of the driver who didn’t: a single mom with three kids in the car. Later, Bryan would have an opportunity to thank her in an unexpected way. Also, we talk with David Bennett, a driving safety expert who explains the importance of your tires when it comes to making your vehicle “road ready.”

From a crowd of onlookers, one person steps forward to help. A teenage girl named Maddie walked to a highway overpass and stopped. As dozens of cars sped past, she climbed a railing, looked over the edge and considered stepping off. A few cars stopped then and people began to gather, but only person, David Johnson, sat down and talked to Maddie. That conversation led to a scream, a laugh and eventually a hug. This is the story of how someone was saved and someone else was changed. We also speak with Martha Thomas, the mother of a young woman who took her own life and the co-founder of an organization called “The Defensive Line.”

A leisurely float with friends nearly ends in tragedy. On a hot summer afternoon, Abi Sherman and some friends decided to cool off by floating down the Snoqualmie River in Washington. Growing up in the Pacific Northwest, she had plenty of experience in rivers. This time, however, everything went wrong. Her tube got stuck on a stump and she slipped into the freezing cold water. Without a life jacket, she was unable to stay afloat in the fast-moving river and her friends were too far downstream to help. As she was tossed by rapids and smashed into rocks, a stranger came to her rescue. We also talk with Peg Phillips, a boat safety expert, about what you can do to stay safe in and around the water.

Social media comes to the rescue. Stacey Eno loves to travel. Her friend Mikey does too, and so they made plans to meet up and explore Bali. After settling into their hotel, they decided to take a scooter to the town of Ubud for dinner. As they returned to the hotel in the dark, they veered off the road and tumbled into a ravine. They were left there for hours, critically injured, unable to move. Mikey was, however, able to send a six-word Facebook post. That set in motion hundreds of people trying to help. In the end, it was the unrelenting effort of a freelance writer in the Poconos that led to their rescue. We also talk with world traveler Jessica Nabongo about what to do when things go wrong in a foreign country.

Something good emerges from something awful. Chantal Melanson was a country girl from Canada. Austin Monfort was a college student from California.

The mass shooting claimed the lives of 60 people. The story of how Chantal and Austin escaped, helping another along the way, is terrifying and, ultimately, heartwarming.
