After the opening sequence with Bella and Edward getting married in front of their friends and family, the video cuts to a love story between Mars, who recorded the track especially for the Bill Condon-directed flick, and his lovely leading lady.
Bruno and his onscreen love experience the many joys, trials and tribulations of being in a relationship. And as is often the case in real life, things starts out cute; every little moment and snuggle is more romantic than the one before. Bruno goes out of his way to court his female friend, even holding a private screening of "Breaking Dawn" to woo her. They share kisses as footage of Bella and Edward's honeymoon flashes on the wall. But at some point, the pair begin to fight, though Bruno isn't going to let her go that easily: He uses his songwriting skills to persuade her to stay with him.
The heartbreak expressed on the track is mirrored in solo shots of Bruno standing around looking sullen. As the video closes out, we see that the song Bruno wrote while his lady was asleep turned out to be romantic enough to win her back.
In the final shot, Bruno stands alone while rain hits the window behind him and sings, "Cause there'll be no sunlight if I lose you, baby/ There'll be no clear skies if I lose you, baby/ Just like the clouds, my eyes will do the same if you walk away/ Every day, it will rain, rain, rain."
The highly anticipated fourth film in the "Twilight Saga" series opens November 18.
