Sometimes life takes an unexpected turn, as in the morning Casey Schrager is a vice detective working undercover as a hooker by the Lincoln Tunnel and later finds herself a part of the hugging squad because she is considered one of the few honest cops and Lt. Little wants to clean up the precinct. As Casey gets to know her new co-workers she discovers that each one has their own sense of humor and their own secrets.
Sgt. Brown has the hots for Det. Beaumont. Det. Delahoy has a brain tumor but wants to die in the line of duty. Det. Banks just celebrated his 52nd birthday and is afraid he won't make it to 53 because that's how old his father was when he died. Det. Cole is very religious but seems to have had a shady past.
Casey herself has her own secrets, she grew up as a member of New York's high society and didn't like that money can buy justice.
