Sneakers (movie)
Fake FBI agents kill Gregor and kidnap Martin. While kidnapped, he again meets Cosmo, who Martin thought had died in prison.  While in prison, Cosmo got involved with organized crime, who helped him escape and get wealthy. He wants to use Janek's box to ruin the world economy.  He asks Martin to join him. Martin says no, and so Cosmo uses the box to break into the FBI's files to add "Martin Brice" as a known alias to Martin's record. Martin is knocked out and taken back to the city.
