The Vanishing Man 1997 on netflix

While Nick Cameron is returning to England from the continent with mysterious cargo in the cabin section of his small aircraft, he is thrown off-course by a severe electrical storm and loses radio contact. To his surprise and horror, he is arrested upon landing and accused of being a traitor in connection with the cargo he has been carrying – which, unknown to him, contained plutonium. Although he pleads innocent, Nick is not believed and is sentenced to a long term in prison. While in prison, he is subjected to special experimentation at a mysterious laboratory – with one unnerving, and unexpected, side-effect of the experiments being intermittent invisibility. —David McAnally
