Unfortunately Femboy, yes, the camp is going to break her (somewhat) and mold her into a submissive slave. It was what Kevin found that she wants. The camp is design to turn slaves (male or female) into submissive's for their Master or Mistress. What Kevin is unsure of is if he can be the kind of Master Marissa hopes for. He will be doing a lot of studying up on being a proper BDSM Master for her. However, as she is going to be broken and remolded, he is worried about how she will be mentally after her return.
So, you were actually correct in your first belief of what the camp is about and the purpose of sending her there.
