Who are the Avenging Blowfish? Ask Doyle Coldiron, an agent with an attitude. He's just a lovesick guy with a submachine gun under his blue blazer - hardly your usual Secret Service type.

It's just the beginning of a hilarious chain of events involving terrorists, animal rights activists, a Stealth kite, a tipsy ambassador who plays Cole Porter tunes, and a covert baseball game against the CIA.
