A truck driver stopped along along I-15 north of Las Vegas during Tuesday’s flash floods there captured a scary incident on his smartphone.

About one minute and 30 seconds into the footage, a man charges into the floodwaters to help an elderly couple whose van was immersed in a raging current in a washed-out median. The man disappears into the van before it plunges over a waterfall into a ravine below.

That’s where the footage ends, but incredibly, the Nevada Highway Patrol says no one was seriously injured.

According to a local Fox affiliate, after the van fell, onlookers were able to save one passenger by lowering a rope to him, and emergency crews later saved the woman, who had floated downstream. The man who had attempted to play hero survived by grabbing onto a bush alongside the rushing water.

The deluge, which was a byproduct of Hurricane Norbert, caused extensive flooding in parts of Nevada, Utah and Arizona. A 50-mile stretch of I-15 near Moapa, Nev., was closed after pavement crumbled during flooding. CWG reported Tuesday that more rain is possible in the region next week.
