A boy named Evan scribbles "I AM BORED" on a library desk.
A friendly stranger with elegant handwriting responds, "Hi Bored, nice to meet you."
For the next minute, you're watching an innocent teen drama unfold, hoping the boy gets to meet this mysterious stranger. Then, you're left hoping they survive.
Be sure to watch the video to the end.
The parents of children killed at Sandy Hook Elementary School have launched in a campaign against gun violence that in just days has been viewed millions of times online.
"When you don't know what to look for, it can be easy to miss signs of someone who is in crisis or planning violence," reads a statement from Sandy Hook Promise, the group behind the "Know The Signs" campaign.
The two-minute-long video released Dec. 2 shocks viewers by showing on-screen the beginning of a school shooting.
Text flashes across the screen, "while you were watching Evan, another student was showing signs of planning a shooting."
Then the video plays again, this time focusing on a boy in the background of every shot.
"People who are at-risk of hurting themselves or others often show signs and signals before an act of violence takes place. When you don’t know what to look for, it can be easy to miss signs, or dismiss them as unimportant, sometimes with tragic consequences," according to sandyhookpromise.org. "It’s important to know that one warning sign on its own does not mean a person is planning an act of violence. But when many connected or cumulative signs are observed over a period of time, it could mean that the person is heading down a pathway towards violence or self-harm. By knowing the signs, you have the power to intervene and get help for that person. Your actions can save lives."
Twenty-eight people, including children, were killed at Sandy Hook Elementary School on December 14, 2012.
