Build a movie plot around this: What is Robledo's job? engineer
The answer to this question is:
It is spring in Paris. Elena [Greta Garbo] is in attendance at a masked ball when the Marquis de Fontenoy [Marc MacDermott] asks her a question. Elena replies that she doesn't love him and never will, and she then runs from him. Making her way through the crowd of boisterous revelers, Elena goes out to the garden where she encounters the Argentine engineer, Manuel Robledo [Antonio Moreno]. They remove their masks and fall immediately in love. They pledge themselves to each other, Robledo gives Elena a ruby ring, and she denies belonging to another man. Unfortunately, it's a lie. Elena is actually married to Robledo's old friend, the Marquis de Torre Bianca [Armand Kaliz], as Robledo finds out the next night when he drops by for a visit.Robledo, Elena, and the Marquis attend a large dinner party thrown by Fontenoy. As they begin a round of toasts, Fontenoy picks up his glass and toasts Elena, whom he calls "the Temptress," "who asks for nothing -- but takes all a man can give -- and more!" As Robledo looks on in distaste, Fontenoy blames Elena for his financial ruin and pulls the jewels from her neck, claiming that he gave them to her. He then promptly keels over dead from the poison he has placed in his own drink. Even though he approved of Fontenoy's gifts, the Marquis is now POed at Elena for disgracing his name. When he complains about not being able to pay his "debts of honor" now that Fontenoy's cash flow is cut off, Elena empties her jewelry box in his lap.Totally disillusioned by Elena, Robledo returns to his home in the Argentine, where the entire village welcomes him back, including his four best friends -- Canterac[Lionel Barrymore], Pirovani [Robert Andersen], Timoteo [Francis McDonald], and Rojas [Hector Sarno] -- and the sweet and demure Senorita Celinda [ Virginia Browne Faire]. Robledo throws himself into the work of constructing a dam, made difficult because the sinister bandit, Manos Duras [ Roy D'Arcy], keeps stealing his horses and enticing his workers away. Still, the work progresses...
