S3·E12 Day Nine

Vinnie is the fall guy in the alleged plot to disrupt the Japanese economy, prompting the Attorney General to launch a classified Senate investigation that could cost Vinnie his badge. Fearing her career is ruined, Kate attempts suicide. After hearing all the evidence, the Attorney General relieves Vinnie of his duties, stating there's enough to prosecute him for treason. Prescott Wilson arrives and places all the blame on Masters. Masters goes off the deep end and kills Strichen. Vinnie is cleared of all charges. (source: http://www.plasticcow.com/wiseguy)
