Published originally in France as TNT #3, La Bete Du Goulag (The Gulag Beast), in 1978.
"It's the ultimate weapon and the Russians have it. It's locked in a cavern where the dead are dangling from wires. It's guarded by a woman whose dream is to experience total sexual ecstasy just once before she dies. TNT's assignment (and he has no choice but to accept it): Go in. Get it. Bring it out."
