"The Debt" - When a multiple homicide and fiery explosion at a drug lab adjacent to Sandburg's loft is attributed to a bitter rivalry between two gangs, Banks asks for assistance from Lieutenant Williams and the anti-gang unit. Soon Ellison, who prefers to work alone, is paired with officer Earl Gaines, a man who grew up among gang members. While their investigative styles clash at first, Ellison and Gaines find they must protect each other as they're drawn into a vicious gang war and a corrupt cop's involvement with the dangerous drug trade, on "The Sentinel" airing WEDNESDAY, APRIL 10 (8:00-9:00 p.m., ET/PT) on UPN.
