What they share
Theysit in Mystery / Science Fiction / Thriller territory. If that's the register that drew you to 400 Days, the second film will land in a comparable space — through a different lens.
What The Philadelphia Experiment is
Off the coast of Virginia. August. A low hum. A new military experiment rips a hole through time. The USS Eldridge returns, bristling with weaponry and malevolent energy, threatening to obliterate the present. One man knows how to stop it. A SyFy vision of temporal paradox.
