Baby Shower (2011)

Four ex classmates, Ángela, Olivia, Claudia and Manuela get together to celebrate Ángela's pregnancy at her country which is located one hour away from the city. It has been a while since the four of them saw each other for the last time and one recently committed betrayal threatens to destroy their long and deep friendship. The revelation of a dark secret and a series of violent deaths transform the baby shower into a nightmare. A very disturbing one.
