function

I was calculating the Fibonacci sequence, and stumbled across this code, which I saw a lot:

    int Fibonacci (int x)
{
    if (x<=1) {
        return 1;
    }
    return Fibonacci (x-1)+Fibonacci (x-2);
}

What I don't understand is how it works, especially the return part at the end: Does it call the Fibonacci function again? Could someone step me through this function?
