 Zain meets with Jordan Tomlin again who tells him he knows how to find one of the missing Mach-10s. Shots are fired at a local community centre during a DJ competition. A victim and a witness are trapped inside, but Superintendent Okaro stops anyone from entering until armed backup arrives as the gunman could still be in the building. Lewis is worried his cousin Dominic could be involved as he was meant to be providing security to the event, but apparently left minutes before the shooting occurred. Dominic tells Lewis that a cop from Sun Hill was cutting deals with Jordan.
