Reversion is a computer animated short film directed by Giancarlo Ng and produced by The Magic Movie Machine, a selfdescribed collaborative animation team.
The short film opens with an unidentified soldier infiltrating the facilities of a company known as Ethercorp. Though the lobby is badly damaged, a stillfunctional computer display reveals the facility to be a medical research centre, located in the Congo. The soldiers helmet also bears Ethercorps logo. As the soldier downloads tracking software from the computer, a reptilian creature lurks in the shadows above. Just before the creature strikes, the tracking software warns the soldier of its presence, and the creature flees under gunfire. The soldier chases the creature though several offices and medical labs, before losing it in a dark corridor.The soldier emerges from a duct in the floor of another corridor, and enters a security room containing a holographic projector. The soldier removes her helmet, revealing herself to be a young woman. By viewing the holographic records, she discovers footage of a human test subject being administered an injection, which triggers a metamorphosis into the creature she had been pursuing. In shock, the soldier leaves her helmet in the security room to record the footage, and enters an elevator. ........
