If you've come this far keep watching HILL STREET BLUES season 5. It will not disappoint.
This is the season of the urine test (freaking out a handful of Hill Street cops); a new roll call sergeant (Robert Prosky); and Jennifer Tilly playing a ditzy, sexy (imagine that) rich, ex-mafia socialite type. Who from the Hill Street will she soon be dating? Garibaldi, now a regular (played by Ken Olin)?
Also a regular for HILL STREET BLUES season 5 is Patsy Mayo (Mimi Kuczyk) and her early strange and uncomfortable relationship with Chief Daniels (Jon Cyphers).
Lucy Bates (Betty Thomas) considers adopting a young boy whose mother is a drug addict.
Action still aplenty. Humor is still here for season 5, too.
Oh, I was a little it surprised how this show (over 7 seasons) had some actors reappearing in different roles (see CCH Pounder: hooker; mom, Kene Holaday: black coalition; homeless dad ... ; and the kid that plays Lucy's adopted son).
Might be worth noticing for worthless, "did you know....?" trivia points.
