The uniforms are on strike, and the detectives must wear uniforms and go back on the street, all the while solving the case of the ""Don Juan Strangler."" This is the first episode in which Cagney plays poker.

The ladies happen on a porno movie filming, and the next day the leading man dies. The female star would make a great witness, but she doesn't want to talk

This time it's clear who the bad guy is. But he's being pursued for bail jumping by a bounty hunter. The bounty hunter not only has a legal right, if he can find him, but he makes a point of irritating Cagney.

When an abandoned infant is turned in, C&L go to work on a baby-broker scheme. The baby is deaf, and Mary Beth wants to take it home for child #3. (This was shown before Tyne Daly's pregnancy.) In the B plot, Cagney is dating a glamorous playwright, but he doesn't think much of her career.

Cagney gets show by a bad guy early in the episode. Not to worry, she solves the case from her hospital bed. She has to, because Mary Beth gets stuck with a real dweeb as a replacement. In a role reversal, Mary Beth is the ""hot dog"" and the guy is only interested in getting home on time

The crime story is a sequel to #16 (slumlord trying to get rid of tenants.) The witness has died, since the defense strategy is to stall, so C&L have to find new witnesses.
