In 1692, in the Ipswich Colony of Massachusetts, five families of powerful witches commit to a covenant of silence to protect themselves against the witch hunters, but one of the families transgress their pact and is banished from their lands. Along the centuries, the power and the covenant are transmitted through their descendants and when the eldest son is eighteen years old, he ascends to a higher power. However, the use of magic addicts and if used in excess, ages the warlock. In the present days, four wizards teenage friends are in high school and their leader Caleb Danvers is close to his eighteenth birthday and consequently to ascend. He has just met Sarah Wenham and they are dating, when the appearance of darkling and supernatural dreams haunt the group. Sooner they find an evil warlock, descendant of the fifth ancient family that wants to strip Caleb's power.
