一名警探在调查一宗毒贩谋杀案时，发现自己身处在这一生最为危险的一个案件中心。她身边的人都没有发现，她就是警方以及杀手都在追查的那名关键证人。

　　Bulletproof follows two meijubar.net cops, Bishop and Pike, as they chase down hardened criminals in London's East End. On the surface Bishop and Pike have a lot in common they are cool, smart, unapologetically street-wise and tough; they share a deep, fraternal relationship - and are always there for each other. However, they come from very different backgrounds and their personal motivations and emotional lives outside the police force differ as a result: Pike is an aspirational family man, the son of a decorated police officer who's determined to follow in his father's footsteps, but not be in his shadow. Bishop grew up in care homes and on the streets, and never knew his father. Despite these differences Bishop and Pike are bonded by the same moral code and work brilliantly well together even when the chemistry between them looks set to explode.
