Ive seen this movie trailer in the television and I think it might be worth it to watch. The movie title is "The Covenant". Based on the trailer I think its about these five magickal families who made a covenant between them during the burning times in Salem. Well, four of the families got along pretty well but one family craved for more power, and because of that they were banished from the covenant...

About three hundred years later...I guess... there's this group of 4 teenagers (all males). Each one is a direct descendant of the four magickal family who co-existed quite harmoniously. They were still just the kind of warlocks who'd use their powers for fun, yet benign way (or so I think).

Their lives soon will be burdened by the return of a descendant of the family who had been banished by the coven. The warlock's goal is too steal their powers one by one and to destroy their covenant...

 Note: I really have very little idea of what the movie is about so I guess dont trust too much to things that I have just said.
