Office worker Mary Briany finds out she is being demoted by the boss she secretly loves in order to make room for his girlfriend. She tries to commit suicide by jumpinginto the river. Tony Woodward is driving by and rescues her, much to her annoyance. He takes her back to his mansion, but he and his butler Godfrey have great difficulty getting her to behave. Meanwhile, Tony is to be married the next day to childish heiress Vera Barton. She reveals to Tony's friend Lord Rufus Paul that she plans to change Tony's lifestyle completely - no more smoking or drinking. Her millionaire father promises his nearly penniless future son-in-law 5000 pounds to pay for a partnership in a company. Later, Mary crashes Tony's bachelor party, dressed as a man in his younger brother's clothes. The next day, Vera and her father find Tony, Mary, and his friends passed out on the floor. As a result, Vera breaks off the wedding. With only £300 and deeply in debt, Tony proposes a suicide pact to Mary. They will fly to Monte Carlo to try to win a fortune at the casino. If they lose, they will kill themselves. The first day does not go well. They are ready to jump off a cliff when a gentleman finds them and gives them £20 they did not know they had won. On their second chance, they split up to gamble. Tony loses, but Mary has an incredible lucky streak and wins a large amount of money. Meanwhile, Vera decides she wants to marry Tony after all. Rufus brings news about Tony's whereabouts, and they go to Monte Carlo. Vera embraces Tony before Mary can tell him the good news. Heartbroken, Mary climbs out on the hotel ledge, but Tony finds her and tells her he loves her.
The film was one of a number that Douglas Fairbanks Jr. made in England. It was produced by Irving Asher of Warner Brothers, who had a brief to make 20 films year under the British quota system. Asher had helped finance some films Fairbanks Jr. produced in England for his own company; in return for the loan, Fairbanks Jr. agreed to appear in the next film Asher produced, which turned out to be Man of the Moment. His co-star, Laura La Plante, was married to Asher. The films failed and Fairbanks was broke. Fairbanks later wrote:
Professionally, Man of the Moment was not at all what I should have done in that period. But Irving hoped that with my name and Laura's, a good supporting cast and direction by an ex-Hollywood comedian whimsically named Monty Banks, Warners would overlook the picture's quota category and release it in the States and Canada. Although they never did, I had the best time imaginable making the movie.
