Something fishy's going on at Sunnydale High -- the swim team is winning meets. Everyone at school is hyped up about the team's success. Even Principal Snyder (Armin Shimerman) asks Willow (Alyson Hannigan) -- still teaching Jenny's (Robia La Morte) computer class -- to give a swimmer a better grade. One student, however, is not so happy with the team -- Buffy (Sarah Michelle Gellar). After a swimmer tries to grope her while on a date, her slayer sense is sparked. Her suspicions are magnified when two swimmers end up being skinned alive. Meanwhile, another swimmer, Gage (Wentworth Miller), is bitten by Angel, who spits out the blood in apparent disgust over its taste. Everyone suspects the swimmers of using steroids. Later, after Gage transforms into a fish-man or "gill monster," the truth about the swim team is clear. Also, Willow is made a permanent computer teacher for the rest of the season.
