It was the day before Cranky and Mathilda's Wedding party in Ponyville. A pony family was on a vacation in the mountains above Canterlot  the week after the Gala. The colt of the family took a camera with him to film the whole vacation. One morning had the ponies been lost, as suddenly dead birds felt down all around. Later on were the ponies reaching a tunnel. There were a lot of empty emergency carts in the tunnel. The police ponies and some guard ponies had seemed to be there, and they were gone too. Police and guard weapons were dropped on the ground.

"Hello, I wonder if anypony is here." did the father shout.

"Strange, it seems like everypony including those in the emergency carts just ran in a rush." the colt said.

The ponies wandered through the tunnel. At last had the ponies been seeing something move in the tunnel.

"Hello." did the ponies shout.

But none answered them. Now the family could rememeber that other ponies told about strange lights from above in these mountains. The ponies tried to run, as they saw a thing none of them had seen before. It was a grey and very skinny naked entity that walked on two legs, and it made loud noises that an animal could not  make. Suddenly were the ponies attacked by the unknown grey entity. The camera the colt had showed a distorted and blinking screen. Then was the camera dropped under the attack by the unknown entity with two legs. The six ponies was about to prepare for the Wedding with Cranky and Mathilda. A letter came from Princess Celestia.

"This is top secret, so come and meet with the royal guards today." Princess Celestia wrote.

The ponies had to skip the Wedding, and meet with the guards. Twilight told Cranky and Mathilda they could not come to the Wedding, as they was sent out to a top secret meeting in Canterlot. As they met with the guards were they told to get in hazmat suits, and follow them up to the mountains where a pony family were told to be abducted by an entity. In the meanwhile were the citizens of Ponyville trying to make it on time to Cranky and Mathilda's Wedding.
