Wholesome 15-year-old Army Juergens finds out that she's pregnant, sparking panic among her two best friends, Lauren and Madison. She won't tell them who the father is, but we catch on when Ricky, fellow marching band member and "drummer," tells Amy he won't forget that special night they spent together at band camp.
But Ricky has his own problems. His girlfriend, Adrian, is about to stand him up to go on an illicit date with the school football star, Jack. Jack's a devout Christian, just like his beautiful, virginal girlfriend, Grace Bowman, but he finds himself torn between his manly instincts and his promise to God (oh yeah -- and his girlfriend).
Meanwhile, Ricky's also putting the moves on Grace -- can't he just stick to one girl? Apparently not, as we learn from a conversation he has with his shrink. But in that some conversation, he also reveals that he spent time in a foster home, thanks to his abusive dad.
But Ricky doesn't know that Amy's pregnant. She doesn't know who to tell first -- a doctor, or he parents? but before she has a chance to break the news to her family that their "good girl" is not so good, Ben calls to ask her out on a date. He's even joined the marching band just to get closer to Amy -- he's actually got a thing for her now. Too bad he doesn't know her big secret, though he does notice her looking at Ricky from across the room. So do Lauren and Madison, unfortunately, and they put two and two together.
But where are Jack and Adrian during all this? Oh, just making out in the church hallway. Unfourtunately, Tom, Grace's brother, walks in on them and screams. Grace and Ricky discover their two-timing significant others while Amy and Ben, oblivious to it all, finish up their slow dance as the world falls apart around them.
