Watch CineCalidad. A secret government research project tries reviving the World War II "Philadelphia Experiment," which was an attempt to create a cloaking device to render warships invisible. When the experiment succeeds, it brings back the original ship (the Eldridge) that disappeared during the first test in 1943 - which brings death and destruction to the 21st century. It's up to the sole survivor of the first experiment and his granddaughter to stop it.
