When looking for something to do on a dull Friday night, 5 friends find a radioactive rock in the woods, which could grant them anything for a limited amount of time. Now, they must protect the rock and themselves from the government.

I agree with NB ... omit "On another boring Friday night". Good observation NB!

I also like this idea and agree with what Screenwriters Anonymous said above, but do you have to include the part about Friday night? Can't you just ditch that and begin the log line with "Five friends... "? That way you would cut down on the word count and get to the interesting stuff faster.

I posted a reply earlier, but for some reason it didn't do it. So I'm trying to remember what I wrote. I love this idea because it can go in any direction your wild imagination will allow. Here's a clean up and suggestions to consider:

"On another boring Friday night five college friends stumble upon a radioactive rock that grants wishes, but for only a brief time. Now they must protect the powers of this unearthly rock and themselves from __________________."

The antagonist will determine the genre of your story. For instance:

1. A government syndicate like the "Axis Powers" (Germany, Italy, Japan during WWII) will give a point in time reference while providing the urgency of their mission using this historical significance. >> Action/Adventure

2. A war-mongering weapons manufacturer led by a vindictive executive. >> Thriller

3. Their significant others (i.e., boyfriends, girlfriends, spouses) >> Comedy

4. Or the second sentence could read, "But now they must protect the powers of this unearthly rock from each other." >> Horror?
