Who is Alpha? Batgirl is trying to find out, which she is taking great pride in, being a new detective and all. Batman and Oracle sends Cassandra Cain out to stop a shipment into Gotham, which Batgirl believes is sending her away from the direction of the case, but is actually directing her straight towards the bull's eye! The only problem...the Bull has amnesia. Let the spy/gangster/on the run story begin.
