CID's raid goes pear shaped after the disappearance of Marek Jankowski, and the shooting of informant Cezar Sobiesneki. Cezar's niece, Marek's sister in law Julie, accompanies him to hospital where he dies. Julie blames Carter for Cezar's death, and things get worse when Carter lets slip he killed her husband. When Marek attempts to abduct Julie's son Lukas, Carter convinces her to help him find her other son Pavel, prime suspect for Cezar's shooting, before CO19 do.
