In the backyard of a Southern California home, a group of family, friends and strangers come together to celebrate the wedding of two people in love, but each brings with them conflicts they can't leave behind.

The bride's brother Ian brings upheaval as he shakes off responsibility. Kristy, the photographer, is overwhelmed by her anxiety. The whole foundation of Leah's life has been destroyed, distracting her from her critical job as wedding coordinator. Amber, the maid of honor, fights to keep a smile on her face as her loneliness crushes her. Dylan, the waiter, tries to balance two warring demands on him. The groom's grandfather, Marshall, is looking forward to the day with his family. And Sophie, the flower girl, seeks the attention she never gets from her mom.

As the wedding day progresses, each must reconcile their expectations of the day with the new reality. All set in one day, No Day Like Today explores how just the tiniest gesture can make a difference and how one single day can change everything
