She is a member of the Zeta Rho Pi sorority at California University in which Naomi Clark joins after getting denied entry at the Kappa sorority by Holly Strickler. Alexis is the deciding vote in Naomi getting in and comes to Naomi's house to live.
She has tattoos and pet snakes, wanting to bring them over to put in the pool, but Naomi nixes that idea and offers to give the entire sorority a makeover. She is among the girls who attend a big mixer in a toga after Holly tricks Naomi into believing it is a toga party. She leaves with the sorority after they learn that Naomi used them and referred to them as losers.
However, after having a meeting, Alexis reveals she got a number of some guy with a matching dead unicorn tattoo, which she reveals was one of her better nights. She bands with the other girls to swear revenge on Holly and forgive Naomi.
