Kicked out of the military for brawling, what can three friends from different countries do to make some needed money? Fast? With nothing in their future, Former US Marine Charles, ex-SAS Booker, and ex-Australian Army Roo decide to give the Zoo a shot. Without the contacts, without backing, without knowing what they are getting into, they scramble to get their foot in the door to even make rent in one of the most dangerous areas in the world. With high rewards comes high risk. Can they learn on the job, where failure means death? Relying on their training, they will scratch, claw, and take the most dangerous jobs to prove themselves, but will it be enough? Can they fight the establishment and the Zoo at the same time? And what the heck's up with that puppy they found?
