Pablo Hernandez Sustaita

Hello, I would like to get information on my g-g-grandfather's baptismal record. I found him under the name of Pablo Hernandez Sustaita. The date of his baptism shows as Feb. 6, 1851. His parents were Pedro Hernandez and Clara Sustaita. I would like to know if this record is avaliable online and if so, how do I view it? I have a source film # 710727. Will I need to request this film from an LDS center? Any information would be most appreciated. I apologize, but I am still a genealogy novice.
