Marty, a butcher who lives in the Bronx with his mother, is unmarried at 34. Good-natured but socially awkward, he faces constant badgering from family and friends to get married but has reluctantly resigned himself to bachelorhood. He then meets Clara, an unattractive school teacher. Realising their emotional connection, Marty promises to call, but family and friends try to convince him not to.

Scriptwriter Paddy Chayefsky's solid dialogue is bolstered by strong performances from Ernest Borgnine and Betsy Blair in this appealingly low-key character study.
