Farmer Gonzalo, the convent's milk supplier, is moving to St. Thomas and can't take Alicia, his beloved cow with him. Sister Bertrille decides to buy Alicia for the convent as a cheap, constant and reliable milk supply for the kitchen and for the children's needs. None of this comes to fruition as as soon as Alicia reaches the convent, she stops providing milk. The Reverend Mother finally gives Sister Bertrille an ultimatum: find another home for Alicia, or off Alicia goes to the slaughter house. When Sister Bertrille can't find another suitable home for Alicia, Sister Bertrille talks Carlos, or rather talks Carlos' girlfriend Danielle, into giving her and Alicia a ride on Carlos' yacht to St. Thomas to go see Gonzalo, who thinks he can solve Alicia's lack of milk problem. They all think it's Alicia being homesick or at least being family-sick for Gonzalo. However they all discover that what Alicia was missing was music as Gonzalo always sang to her while he milked her. So Alicia has found a new home at the convent with a new source of music. Carlos is given a reward for taking Sister Bertrille and Alicia to/from St. Thomas: Alicia's first glass of convent milk.
