Carlos has failed in show-biz and currently works as a waiter in a Mexican restaurant. There he meets Alex and dumb footballer Bruce celebrating their engagement with her parents. Alex' father is less than thrilled of her fiancée and says he'd rather accept anybody else. Eventually Alex hires Carlos to present him as her new fiancée.
The show centres around four main characters who are members of an elite New Zealand taskforce based in Auckland NZ, intended to be a combination of police and customs officers. Despite being an elite force, they are, as their commander Ron Maddock reminds them, under-funded, under-resourced and under the hammer. Because of this, the Roughies (as they are called) have to make sure that they perform exceptionally well to avoid being canned, as they are, after all, an experiment. Their members are: Detective Sergeant Danny Wilder, Senior Customs Officer Jane Durant, Detective Constable Zach Wiki and Noel Bullerton.
