A 10-year feud between two families -- the Gennaros and the Bentons -- over their rival ice cream businesses gets personal and nasty as the two vie for the same area in London. At the height of the feud, in 1996, there were a number of mystery raids on both family businesses, and during one of the robberies Andy Benton was shot. The original investigation into the shooting focused on suspects outside of both families, but on witnessing the ongoing tension, rivalry and hatred between the two, the UCOS team look closer to home when they reopen the case.
A motley crew of retired police officers re-opens troublesome cases that were never laid to rest.
