Gnomeo & Juliet is a 2011 computer-animated family comedy-drama film based on William Shakespeare's play Romeo and Juliet.Miss Montague and Mr. Capulet are two elderly people who despise each other. When they leave the garden, objects come alive in both their gardens. The Montague garden is filled with blue garden gnomes, and the Capulet garden houses red garden gnomes. Later, both blue and red gnomes attend a lawnmower race. Representing the blues is Gnomeo and representing the reds is Tybalt. During the race, it looks like Gnomeo is winning; however, Tybalt cheats and wins the race, destroying Gnomeo's lawnmower. Gnomeo and his best friend, Benny insult Tybalt for cheating, but Tybalt ignores them. Benny watches Miss Montague ordering a new cheap lawnmower, disappointed.
Later that night, Gnomeo and Benny, infiltrate the red garden in disguise, with blue spray cans. Benny sprays Tybalt's well and accidentally triggers a security light in the process, alerting the red gnomes to attack. During the escape Gnomeo ends up in a nearby neglected garden. He bumps into a disguised Juliet, the daughter of the red gnomes leader Lord Redbrick. Juliet is attempting to retrieve a unique orchid, and the two romantically fight over it. They each discover the other's colour before fleeing the garden. When they both go back to their gardens, Juliet tells her frog friend Nanette about her newfound love. Nanette states that the relationship is romantically tragic.
Benny, meanwhile, buys the Terrafirminator lawnmower using the computer and cancels the order of the Kitten Clipper, to get revenge on the Red Gnomes, despite Shroom trying to convince him that Gnomeo is still alive. The Terrafirminator goes out of control and destroys most of the two gardens. Gnomeo makes it back to Juliet to try to un-glue her, but he is unable to. She tells him to go, but he refuses, and the two share a kiss just as the lawnmower crashes into the fountain, self-destructing in the process and the William Shakespeare statue in an "I told you so" moment of confidence. Everyone believes that both Gnomeo and Juliet are dead. Lord Redbrick and Lady Blueberry, both realizing that their feud was responsible for this, decide to call a truce. Suddenly, both Gnomeo and Juliet climb out of the rubble and are both fine just as Miss Montague comes back to see if the Kitten Clipper lawnmower has arrived and so was Mr. Capulet who are soon horrified to see the destruction. The film ends happily with Gnomeo and Juliet getting married on a purple lawnmower, which symbolizes the truce.
