Plot
Jeckie Farnish (Calvert) has grown up in a grindingly poor household, and as she reaches adulthood falls in love with a local grocers son. She is loved by her childhood playmate Joe Bartle (John McCallum), but takes him for granted and feels that he lacks the spark or ambition to match her determination to make something of herself. Instead she pursues Albert Grice (Hubert Gregg), son of a wealthy grocery store owner, and believes they have an understanding. She is horrified when Albert goes on holiday and returns newly married to another woman, heartbroken, she resolves to do whatever is necessary to claw her way out of poverty.
Seeing a possible payday as compensation for her disappointment, Jeckie sues Albert for breach of promise and emotional distress, and after she plays up her status as jilted victim to a local lawyer, she is awarded a considerable out of court settlement for damages. Seeing the chance for revenge, she uses her windfall to set up her own grocery store, directly opposite that of the Grice emporium. By undercutting on prices and offering customer perks, she soon succeeds in poaching nearly all of their business and starts to accumulate a tidy sum in profits. Her ambition however stretches beyond a grocery store and its relatively modest financial potential. She is intrigued to meet a handsome stranger Charles Mortimer (Rennie), who tells her that there are large deposits of oil on the edge of town and he is looking for a financial backer to help him exploit them.
