Skeptical Augury

A strange creature roams the night, and then vanishes.  A woman is abducted from her home, but the footprints in the area are not human.  A man's dreams of monsters become real.  These apparently unconnected events bring together a group of strangers, who struggle to understand what is happening.  When they meet a trio of monster hunters, they are skeptical, at first.  Eventually it becomes clear that mysterious forces, possibly from other dimensions, are engaged in a struggle, and they are unwitting pawns in this conflict.   This is the story of how they choose not to just be passive players in this cross-dimensional campaign, and join forces with unexpected allies to stop an invasion of Earth before it happens.
