The Invisible Man (2000) : 1x19

Kate Easton (The Value of Secrets) is on the run from Allianora. Easton is grabbed before Darien can get her to safety and put into cyrogenic suspension by Allianora's (as yet unidentified) employers. The people Allianora work for are collecting scientists for future use under their control. The Agency manages to capture Allianora, but she proves impossible to crack. So Darien secretly cuts her a deal: he'll betray the Agency and help her escape if she'll betray her bosses and help him rescue Kate. Both of them end up double-crossing each other, and Darien ends up in a cyrogenic tube when Allianora scrambles his tracking signal. He manages to escape using his invisibility and rescue Kate. However, when he returns with the Agency, the warehouse and the remaining scientists are gone.
