Okay, here's an example storyline, if anyone's unhappy with it then just let me know.
It is the year 1942, the war has been going on several years now and you can't see any end coming soon. You are all mere Soviet factory workers producing endless amounts materials for the Red Army in an isolated part of what is now known as Latvia. One day you turn up for work and find the area surrounding the factory a desolate wasteland. In place of you factory there is a crater the size of several football pitches, but closer inspection reveals an object in the center of the crater. A large amount of the material you had been producing for the Red Army was piled up high and seemingly intact. One of you cuts a chunk of the leathery substance from the pile and puts it in you pocket, intending to keep it as a souveneir of whatever this turns out to be. You were all transfered to another factory in another isolated area almost immediatly, seemingly as if there was never anything that had gone on. Suddenly the windows shatter and the doors burst open. Masked Soviet Guards rush into the room, opening fire on everyone and causing mass panic tin the crowded factory. You manage to drop to the ground and out of the way of the fire before rushing off out an open door and running for your life. You make it about half a mile through the flat land before collapsing into a bush and hiding there. After seeing the Guards ride of in covered trucks you stand up and prepare for a long walk back to your home. You grab a newspaper from the stand and open it up to find in front of you a story about how many factory workers and their families had been killed in a German attack during an open day at the factory. You all rush home to find your accomodation empty and a large man standing in the center of the room.
There's something I quickly whipped up, it will need some tweaking and editing but it gives you the general idea of the storyline.
