The answer is no.
There are places online that you can see (bad) samples if you wish, but its your own creation. Part of the law school process is learning (painfully) things on your own and figuring out what's important and not important. As such, that's a decision no one else can make for you.
To get you started, I'll give you a small sample of the contents, which will duly be criticized by everyone who reads this post.
Caption - case name, citation, court, year, page in casebook.
Facts - what happened (a lot of students don't realize how important these really are)
Procedural history - what happeend in the lower courts, who won in the lower courts
Rule - what's the legal principle at the heart of the case
Issue - what is the (current) court deciding in this case? (Look for the word "whether")
Holding - how the court applied the rule of law to the facts of the case
Rationale/Analysis - What made the court decide the way it did? What legal or policy justifications did the court invoke?
Synthesis - What now? What will the policy ramifications of this decision be? How will society change as a result? Who is the winner, who is the loser?
If you want, go find yourself a little case, read it very thoroughly, brief it, and pm your brief to me and I'll give you some feedback.
The important thing to remember is, case briefs are for your own good - professors just don't give a crap if it sucks because they don't read or otherwise look at them.
