Rather silly body-swap premise dressed up as serious science fiction.
There's a sort of Mexican stand-off at the end by the trio of male protagonists, all in the wrong body. The technology that made this possible is flimsy to say the least, put together in a barn in Texas.
It's possibly as potentially confusing as a Christopher Nolan plot, without anything that might be classed as cereb-ral.
It doesn't help that the characters all act like the dumbest person in the lone star state, so that the greatest mystery is really how none of them have worked out what is actually going on.
