On an airplane to Los Angeles, Kate Hazeltine (Julia Roberts), a captain in the U.S. Army on a one-day leave, meets gay man Holden (Bradley Cooper) who has recently become single again. In Los Angeles, florist Reed Bennett (Ashton Kutcher) eagerly proposes to his girlfriend Morley (Jessica Alba) who accepts his offer, much to the surprise of Reed’s colleague Alphonso (George Lopez) and best friend Julia (Jennifer Garner). Julia, a primary school teacher, has recently fallen in love with Dr. Harrison Copeland (Patrick Dempsey) who might just be hiding his true agenda. Meanwhile one of Julia’s students, Edison (Bryce Robinson), is trying to send flowers to his Valentine, while his babysitter, Grace (Emma Roberts), is planning her first sexual encounter with boyfriend Alex (Carter Jenkins). Meanwhile Edison’s grandparents, Edgar (Hector Elizondo) and Estelle (Shirley MacLaine), are facing the troubles of a long marriage while Grace’s friends Willy (Taylor Lautner) and Susana (Taylor Swift) are experiencing the freshness of new love. Sean Jackson (Eric Dane), a closeted professional football player, is contemplating the end of his career together with his publicist Kara (Jessica Biel) and his agent Paula (Queen Latifah). Kara, a close friend of Julia’s, is organizing her annual ‘We Hate Valentine’s Day’ Party but is starting to become interested in sports reporter Kelvin Moore (Jamie Foxx) who has been sent out by his producer Susan (Kathy Bates) to cover Valentine’s Day because of a lack of sports news. Paula has recently hired a new receptionist called Liz (Anne Hathaway) who has recently started dating mailroom clerk Jason (Topher Grace). However, Liz is keeping a kinky little secret from Jason.
