British singer-songwriter Greg Holden just released a music video for his song “Hold On Tight” that contains a powerful message.

The video shows on one random, small act of kindness can change everything.

It starts with a man helping a woman stand up after falling down on the street, and shows the follow up events until the kind deed comes full circle.

As the plot unfolds, you will be moved to tears.
