Stanley Goodspeed is a biochemist and FBI agent who is reluctantly pulled into a dangerous mission to infiltrate Alcatraz Island, which has been taken over by rogue military personnel threatening to launch chemical weapons on San Francisco.
Goodspeed is known for his expertise in chemical weapons and his somewhat nerdy demeanor, which contrasts with the more hardened and experienced military characters around him. Throughout the film, he becomes a central figure in the efforts to disarm the threat and save the city from catastrophe.
Goodspeed Jr is just a kid with the same name as Stanley Goodspeed.
