Cyrus, a young man, living on the western seaboard of the united states is one day handed a vial of liquid of unknown effect and origin by a drug-dealer snooping about his neighborhood.

He deals with the social stigma of being a pony pre-conversion bureau opening and lives with the fact a decent majority of his neighbors are HLF members.
