WATCH: Prepare for an emotional rollercoaster with a Dublin lighthouse backdrop
The video features a little boy named Jacob, who lives alone on an island with his dad - the islands lighthouse keeper.
Throughout the video, Jacob tries and fails numerous times to get people on the mainland to come to his birthday party - using a message in a bottle and a sign.
The day before his birthday, he makes a video on his dad's tablet pleading with whoever watches it to come to his party, because he says "if you're out there, what I'd Love is to share it with people."
As Jacob is asleep, the video starts to get millions of likes, comments and views on the internet.
The next day, Jacob and his dad are standing on the island looking out at the sea. All of a sudden, a load of boats arrive up to the island, filled with people who want to share Jacob's birthday with him.
The video is very heart-warming, and was shot in Dublin, in Skerries, Bray and Howth Lighthouse.
