Humberto Valdez AKA "El Maestro" (Anthony Iava To'omata) is teaching at a small town junior college and he takes his Chicano studies course seriously ... perhaps a bit tooseriously. With the exception of a lone student, El Maestro is considered by the pupils and faculty alike to be a joke and out of touch with the real world. "El Maestro" comes down with a bad case of "Aztec Blood Lust" after being fired. It's a malady that has tragic side effects ... for others. Possessed by a spirit to wreak havoc upon those who have taunted him, "El Maestro" becomes a one-man killing machine. Has an evil spirit truly possessed "El Maestro?" Or, has the pressure of entertaining on the holiday caused him to snap? Can he be stopped? To find out you'll have to watch Cinco de Mayo ... if you dare.
