The Vessel: A Science Experiment

Loosely inspired by the Alien movie but with a cult twist. The idea is that there is a cult that has a purpose to populate the Earth with Aliens by using humans' wombs as vessels.

A scientist uses her own womb to create an alien breed. She managed to develop embryos that are able to grow within a human womb. She has completed her research and decided to sacrifice herself by giving birth to the first alien creature.
