The Brotherhood is a 2001 horror film directed by David DeCoteau and starring Samuel Page, Josh Hammond and Bradley Stryker.
Chris, who has no high opinion of fraternities, gets to know a student of psychology, Megan, who invites him and Dan to a party of Doma Tau Omega, saying that she does not want to go there alone.
Shortly after that, Chris is introduced to parties in the DTO house, where he and Devon drink blood from a girl called Sandy in a way reminiscent of sexual intercourse.
Investigating the book of DTO, Dan is shocked to find photos of Devon throughout the decades of the fraternity's history, completely unchanged.
The student found dead on campus was made to commit suicide, as he was afraid to participate in the ceremony and threatened to go public.
