One moment, a little girl is celebrating her birthday surrounded by friends and family. Within seconds, she is dodging bombs, forced to flee her home and languishing in a refugee camp as war comes to London.
It only takes a minute for this little girl to experience the full horrors of war in Save the Children's video, which shows flashes of the mounting disaster in one-second chunks, as the situation worsens around her and the UK descends into violent chaos.
The video aims to show Britons just how quickly everyday life can be turned upside down by conflict, just as it has been for the children of war torn Syria, where an estimated 10,000 children have lost their lives in the past three years.
The final, chilling, message reminds us: "Just because it isn't happening here, doesn't mean it isn't happening."
