Despite his father Pramod demanding that he accept Laali, Laddoo chooses career over love. The girl leaves her abusive father Ganpat (Saurabh Shukla) wanting to move into Laddoo’s home provided he accepts her and her unborn child. Laali gets pregnant, but Laddoo is not ready for marriage. He manages to win her back and soon they get between the sheets while holidaying in Kashmir. Laddoo’s lie of being a crorepati’s son doesn’t last long, leaving the corporate executive Laali disheartened. There he meets Laali (Akshara Haasan), a regular customer. However, he ends up waiting tables at Kabir bhai’s (Sanjay Mishra) restaurant. Laddoo (Vivaan Shah), son of a Madhya Pradesh bicycle trader Pramod (Darshan Jariwala) leaves home to purse his sky-high dreams in Baroda, Gujarat. A smart title, but sadly, the film turns out to be a proverbial disaster. Harishankar’s Laali replaces begaani, while Laddoo takes the place of Abdullah.
The title is born out of the popular Hindi/Urdu proverb, ‘Begaani shaadi mein Abdullah deewana’ which roughly translates to an uninvited guest out to get some free food. Well, director Manish Harishankar is out to prove us wrong as he scales new heights of ridiculousness with Laali Ki Shaadi Mein Laddoo Deewana. The gatecrasher boy marries the bride, and that is where the fantasy ends. Viewers with some sense of logic have always been baffled by such sequences, but have to come to unwillingly accept them over the years. In the end, all cheer the uninvited hero as he ties the knot with the bride. What's astonishing is that here’s a big fat wedding with hundreds of guests, relatives watching, but neither the groom/bride or their parents care what the guests or the relatives make of this 11th hour groom replacement plot. Often it’s the groom-to-be who unites the bride with her true lover.
However, at the 11th hour, or four pheras (Hindu wedding nuptials) later, the girl would annul the rituals and walk into the arms of her hero. The cliched Bollywood love triangle tales of the 1990s often saw the hero helplessly watching his lady love enter into wedlock with another man.
