"No, I couldn't let you take that chance."

Deanna Durbin witnesses a murder from a train. Thus begins Lady On a Train, a delightfully funny and thrilling film noir comedy and one of Durbin's best films. There's the usual singing and frivolous humor that Durbin is so good at, but the focus this time is on the shady murder mystery, which involves some very strange suspects and all sorts of ulterior motives. Highly recommended.
