After two Texas A&M University coeds are attacked on campus on consecutive Saturday nights, the media dubs the assailant the "Saturday-night Rapist." Detective Margo Cruz, with the University Police, and Detective Alfred Cruz, her husband, with the College Station Police, have their hands full as they attempt to restore calm to the normally spirited and friendly school by identifying the perpetrator before he can strike again. At the beginning of the semester, apartment-mates, Lucy, Beth, and Wanda, entered relationships with new boyfriends, Josh, Leroy, and Bill. Their normal routines of attending classes, working at part-time jobs, studying, dating, and participating in unique A&M traditions are suddenly disrupted when danger strikes close to home. Can smartphones and Facebook help solve the crimes? Is a Facebook "friend" really your friend?
