When American soldier Joe Allen (Robert Walker) arrives in New York City to start his 48-hour leave, he ends up falling in love at first sight when secretary Alice Maybery (Judy Garland) trips over him at the train station. Alice and Joe spend the afternoon together taking in the sights and make plans to meet again later that evening. Alice’s roommate cautions her about spending time with strange soldiers, but she ignores her roommate’s warnings and keeps her date with Joe. Their date continues until very early the next morning and by then, the two of them are already considering marriage. However, they fail to account for how long it will take to get the mandatory blood test and it's a race against time to get the results so they can be married before Joe goes back on duty.
The Clock was the only non-musical film Judy Garland made during her time working at MGM Studios and one of the few non-musicals of her entire career. Although The Clock is a very sweet, gentle tale of wartime romance, audiences in 1945 stayed away because they were disappointed that Judy Garland doesn’t sing in it. However, Garland and Walker are surprisingly charming together, which makes The Clock an absolute pleasure to watch.
