No Hands on the Clock is a 1941 American comedy mystery film directed by Frank McDonald starring Chester Morris as detective Humphrey Campbell.

Private detective Humphrey Campbell (Chester Morris) tracks down a runaway woman, Louise (Jean Parker) and ends up marrying her.

Louise convinces him to take the case after Oscar promises her a fur coat for locating Hal.

In the hotel bar, Humphrey learns that Hal was often seen with a woman, a redhead named Irene Donovan.

A blonde named "Gypsy" Toland offers him a ride to Irene's place, but when Humphrey is spotted by a furious Louise, he gets out of the car.

Louise is ready to walk out on Humphrey, but the police will not let her leave because her husband is now a murder suspect.

Humphrey is cleared of the murder when Police Chief Bates learns that he has a solid alibi.

Then Humphrey figures out why the silver dollar found in Irene's hand seemed familiar: it is the trademark of Red Harris, a bank robber.

Red does not spot anyone he knows and is killed in a shootout with the FBI agents, tipped off by an anonymous phone call.
