Max Thursday, hardboiled private eye, is having a tough week. A simple collection case drags him into a blackmailing syndicate that specializes in murder. He's working night and day - but all the killing characters he runs into try to help him get that needed shut-eye.

Lush blonde Yvonne, draped in a scanty negligee, offers a comfortable divan, a bottle of liqueur (well drugged) and a photographer in the next room who likes to snap compromising photos.

Quincy Day hospitably shares her apartment - with breakfast thrown in. Too bad Quincy is the head of the shakedown mob that has Max worried.

The District Attorney (he has no sense of humor) thinks Max should spend his nights - and days - in jail, claims he's the logical suspect in four murder cases.

The murderer makes a bed for Max in a freezer plant - he'll sleep permanently there!

So Max does his darndest to stay up - at least until he gets the killer behind bars in this fast-paced thriller of an eyebrow-lifting West Coast blackmailing operation.
