With a script that's hazy on explanation, this thriller survives thanks to the pell-mell action that papers over the weak links in the convoluted plot. Watching Keanu Reeves play a scientist seeking to make cheap power out of water is a little hard to take. But after he and fellow researcher Rachel Weisz go on the run from mysterious saboteurs after cracking the formula, The Fugitive director Andrew Davis's muddled suspense tale finally takes flight. Don't think, just panic, as Reeves cashes in on his Speed hero persona in a running, jumping slice of breathless escapism.

At the University of Chicago, a research team that includes brilliant student machinist Eddie Kasalivich experiences a breakthrough: a stable form of fusion that may lead to a waste-free energy source. However, a private company wants to exploit the technology, so Kasalivich and physicist Dr. Lily Sinclair are framed for murder, and the fusion device is stolen. On the run from the FBI, they must recover the technology and exonerate themselves.
