Prologue: The Robbery

LA, USA

The bank is never peaceful. There is always something happening. An angry customer, a toddler throwing a tantrum, customers worried they won't be able to pay back their loans on time, but the employers of the bank were not expecting a large terrorist attack. Occasionally, a criminal underestimates the security of the bank and attempts a robbery, only to be leave in handcuffs a few minutes later. However no one could have prepared for this morning's white mask attack. A large number of men wearing white ceramic masks and armed to the teeth stormed the building, killing all of the guards. One civilian tried to be a hero, running at a man wielding the chair he was just sitting on. One of the terrorists simply smacked him in the head with the butt of his shotgun, knocking him out. He aimed his weapon at the unconscious man, but before he could pull the trigger, a fellow terrorist stopped him.

"Wait! Don't kill him yet, he could be useful."

"Good idea"

A few minutes later, the hostage woke up. He began to stand up but then heard a voice behind him.

"Don't move"

The hostage tried to question the man about why he was being kept hostage, but then realized his mouth was duct taped. He sat back down. He looked around and saw that he was in the vault. The vault, and the two adjacent rooms to it were all heavily fortified. Barricaded doors, Fortified walls, barbed wire and a large number of armed men. There was no way the police or even a SWAT team could save him. He was dead for sure.

Meanwhile, outside the bank, the police had set up a blockade. A SWAT team was outside, ready to fire at anyone who stepped outside. The police then heard a loud voice coming from inside the bank. One of the terrorists must have brought a megaphone.

"DO NOT ENTER THE BUILDING, WE HAVE A HOSTAGE AND WE WILL NOT HESITATE TO KILL HIM IF RESCUE IS ATTEMPTED. WE ARE GOING TO DO WHAT WE CAME TO DO, THEN LEAVE THE BUILDING. NO EARLIER THAN 20 MINUTES AFTER WE HAVE LEFT, YOU MAY ENTER THE BUILDING AND RESCUE THE HOSTAGE. ALL ARMED MEN MUST STAND DOWN NOW"

No one moved. The SWAT team leader radioed to the mobile police HQ and asked the chief of police what to do. The chief of police replied. "Wait, they might have more demands." Five minutes later the voice from inside spoke again.

"I REPEAT, ALL ARMED MEN MUST STAND DOWN OR WE KILL THE HOSTAGE"

The chief of police radioed back to the SWAT leader "Do as he says, I'm calling in team rainbow"
