When J.J. LaRoche's house is robbed, he personally requests Jane's help with the case. While LaRoche was able to shoot and kill one of the thieves in the struggle, he tells Jane that the other one got away with the secret Tupperware box he's been keeping hidden for nine years. LaRoche believes that Jane knows what’s inside the box (Episode 323) and begs him to solve the case before the contents are revealed and his life is destroyed. He’s been building a case against a mole inside the CBI for months, and he suspects that the person responsible for high level security leaks inside the agency is also behind the theft of the Tupperware. As Jane and Lisbon attempt to find the mole and the thief, the rest of the team try to piece together the mystery behind what LaRoche hid in the box.
