THE COVENANT

In 1692, in the Ipswich Colony of Massachusetts, five families with magical abilities, referred to as "the Power", form a covenant of silence to protect themselves from persecution. Four of the five bloodlines survive to this day; one family, lusting for more power, was banished, their bloodline disappearing without a trace until now.
The Covenant tells the story of the Sons of Ipswich, four young students at the elite Spenser Academy who are bound by their sacred ancestry. As descendants of the original families that settled in Ipswich Colony in the 1600s, the boys have all been given amazing supernatural powers.
But their ability to shape-shift, defy gravity and perform superhuman feats of strength comes at a terrible cost: every time one of the Sons of Ipswich uses his magical powers, he ages prematurely, and the temptation to abuse the power makes it more addictive than any drug. What's more, life is only going to get harder for the young friends; at the moment each boy turns 18, he will "ascend," gaining far more potent—and addictive—powers.
With Caleb's birthday just a few days away, his mother Evelyn (Wendy Crewson) is terrified her son will find it impossible to resist the lure of power like his father before him. Caleb assures her he'll be able to handle his new abilities. But will he really? And what if he needs his power to fight an evil force that threatens everything he loves?
As the new school year begins at Spencer Academy, students have gathered for a wild outdoor party to mark the end of summer. Hundreds of feet above the gyrating bodies, Caleb Danvers (Steven Strait) and his three best friends - Pogue Parry (Taylor Kitsch), Reid Garwin (Toby Hemingway) and Tyler Simms (Chace Crawford) walk to the edge of a dizzying precipice and drop unseen and unscathed before casually joining the fray. At the party, gorgeous newcomer Sarah Wenham (Laura Ramsey) is introduced to the boys by her equally stunning roommate Kate (Jessica Lucas). The girls also meet an intriguing transfer student named Chase Collins (Sebastian Stan), who quickly ingratiates himself into the group.
When the police arrive to disperse the partiers, they discover the body of a student, dead of an apparent drug overdose. The school headmaster (Kenneth Welsh) immediately suspects Caleb and his friends are somehow involved. Meanwhile, as Sarah, a former Boston public-school student, tries to adjust to dorm life at the elite prep school, she can't shake the creepy feeling that someone—or something—is watching her every move. Sarah takes a shower after the outdoor party, only that a light bulb breaks and someone/something may be behind her. She sees Reid and they check out the showers, but not finding anything. She goes back into her dorm room.
At the swimming carnival, Chase and Caleb race each other in freestyle, but when Caleb turns his head sideways to take a breath, he sees Chase's eyes black as night making Caleb starting to get intrigued. Caleb and Pogue, sharing a mutual dislike of Chase, goes to the school's office and finds Caleb's file.
Sarah returns to her dorm room after a date with Caleb only to not see her roommate Kate. It turns out that Kate was bitten all over by spiders, which relates to a spell that only the Covenant knows of. Pogue hears of the news of Kate during a meeting with Tyler, Caleb and Reid. The meeting was about Chase, he being the 5th one with powers. It turns out that Chase wanted more powers because he was addicted. Chase threatens Caleb that everyone he loves will die if Caleb does not will Chase his powers right after he ascends.
