The episode starts off with a scene where two girls are shown sleeping in their beds, and it appears that someone breaks into their room. In the next scene, the younger of the girls is shown hiding in the room, and tells the CSIs her sister was taken by a monster. This prompts a state-wide search for the girl, who is a budding young tennis player. Turns out, she had just run off with her boyfriend who had climbed in through her bedroom window. However, it is discovered that her boyfriend, also her tennis instructor, had previously killed several of his young players, and he is taken away, yadda yadda yadda. Not one of CSI Miamis best episodes, but ok nonetheless. Gotta love Horatio at the end though when he puts the reporter in his place.
