Doppelgänger (2012)

Silvia (Sabrina Greve) is an elementary school teacher having a hard time keeping her class' attention in the Brazilian short film O Duplo, or Doppelgänger (2012). That's because outside the classroom is a woman who looks exactly like their teacher, and though Silvia attempts to ignore her double, it isn't long before her double won't be ignored. That's because they're two halves of a whole, and Silvia is terrified of what will happen if all the dark impulses she's been suppressing suddenly take over her life! Sabrina Greve is one committed actress, baring some fantastic full frontal during a sex scene, and also showing her breasts while getting into the shower!
