Gayle, Armstrong and Smith attend an armed robbery at a toy shop, with the manager shot during the raid, but a pursuit fails to prevent an escape. Carter takes charge of the investigation, and CCTV footage appears to show two known thieves casing the shop the day before.

Brown and the sister of a suspect in an armed robbery investigation are taken captive by armed drug addicts.
