The crooks in London know how it works. No one carries guns and no one resists the police. Then a new gang appears that go one better. They dress as police and steal from the crooks. This upset's the natural order of the police/criminal relationship and the police and the crooks join forces to catch the IPOs (Impersonating Police Officers), including an armored car robbery in which the police must help the gangs to set a trap.
The story follows Boris, a charismatic tour guide who unexpectedly reunites with his estranged father Julián. Their tense and emotional encounters explore past wounds and the possibility of forgiveness.
