in this movie a woman lawyer and a guy were chased by some bad guys, these bad guys had a thermal vision. one of the scenes I remember was, the guy was taking a cold shower while the bad guys were watching him from outside of the hotel. and because of a cold shower, he was disappeared from the thermal vision.
“Memoirs of an Invisible Man” (1992)??

I remember the invisible man going on the run with a woman and the bad guys used thermal-type goggles to be able to see him.
