Now a story about a modern day good samaritan, a bus driver doing his rounds on an ordinary day when he sees something others chose to miss and does exactly the right thing. It was all caught on tape and linsey davis brings us his story. Reporter: Call it a real life instance of what would you do? Watch as surveillance video cap tours the moment of a woman standing on a narrow ledge on the other side of the guardrail, apparently contemplating jumping onto a local express way below. This man walks right by, this biker keeps on pedaling but barton pulled over and stops the bus. The woman turns to look at him but doesn't respond. That's when he goes to her. I basically told her there is nothing that serious and where she was was a dangerous place. Reporter: Barton literally talks her off the edge, helping her climb back over the guardrail. Then he sits with her and just talks. I gave her encouraging words. I grew up in a church so in the background I heard my mom's voice. When he gets back on the bus the passengers, mostly high school students, give him a round of applause. The bible says be ready in season and out of season. You have to be ready. If you have time to anything, you have time to do the right thing. Reporter: His co-workers call him big country but across this big country tonight, it's his big heart we'll all remember.
