 It s a very busy time at the Montecito. Not only it s Groundhog Summer, which marks the end of the summer, there s also a SciFi convention and the casino floors are flooded with  aliens . Danny gets a strange call from Delinda who faintly asks for help. It turns out she was drugged and nearly raped. Big Ed wants to do the investigation himself and doesn t inform the police. Together with Danny he tries to find the rapist. Meanwhile Mike Cannon gets suspicious when three MIT students check into the casino. They do not attend Groundhog Summer or the SciFi convention, but say they are going to a technical convention that was a week ago. They also carry rather heavy suitcases.
