Accidental Legend

Some legends are born. Others are made. Sometimes they happen by accident. 

According to legend, Queen Medb once tried to steal the magical Brown Bull of 
Ulster in order to become a god. Cú Chulainn, the powerful warrior, stopped her 
by single handedly defeating her entire army. 

Somehow Medb has returned to modern-day Ireland and is trying to get the bull 
once again. This time it is up to Cú Chulainn's descendant, Cathal Cullen, to stop 
her. The problem is Cathal does not know about his heroic lineage. Luckily someone 
has been drafted in from the fairy world to help him. Unluckily, that someone is 
Filthy Henry.
