After Regan’s car is stolen with invaluable surveillance photos from a stakeout, the thief gives a heads-up to Sweeney’s target.

When the Superintendent finds out that there is a bank robbery in progress on a Saturday afternoon, he assigns Regan to visit an old girlfriend whose apartment is adjacent.

Regan loses his patience with a thug he is questioning about a wages snatch, and soon the press are sniffing round for a police brutality story.

Regan is fitted up by an ex-con to get his daughter's dodgy boyfriend out of the picture.
