A deranged man wants his brother released from prison and threatens to release poison gas in public if he isn't. But there are two problems: the brother may die before the deadline, and the gas canister may also unexpectedly explode.
To get close to a vindictive and paranoid criminal who stole a canister of nerve gas, Lisa poses as a career criminal in a jailbreak. A new IMF member, Bill Williams, impersonates the villain's brother to get close to him. Unknown to the criminal the canister is corroding, and will leak if it's not recovered in time. But that would suit him just fine.—David Foss
