You Light Up My Life

Laurie Robinson makes a living performing in commercials and hosting a children's show, but she dreams of writing songs and singing professionally. She feels constrained by her small-time comedic act with her father Si and longs to focus on her own artistry.

One night at a restaurant, Laurie meets a young film director named Chris Nolan. They share a spark, and she ends up spending the night with him as he drives her back to his apartment.

The next morning Laurie reveals she is engaged and must attend her wedding rehearsal. Chris confronts whether their night was just a fling, and Laurie tells him she cannot see him anymore.

Laurie meets her fiancé Ken Rothenberg and participates in a recording session where she records her song and sings backing vocals. She also directs the musicians during overdubs, showcasing her growing musical talents.

Laurie goes to the wedding rehearsal, where Si has arranged an elaborate setup with an old friend who owns the Wedding Palace. The spectacle underscores the chaotic path toward the wedding.

The next day Laurie auditions for a film that needs a singing voice for the leading lady. The director turns out to be Chris, who is surprised by her presence. He asks to see the songs in her portfolio.

Chris sings You Light Up My Life for Laurie at his piano with a subdued arrangement, then takes her for a walk along the beach. The moment deepens their connection and hints at a collaboration beyond the audition.

Laurie visits her best friend Annie to confess that she loves Chris and may land the lead in his movie. She is torn between love and the career opportunity that awaits.

While Laurie considers calling off the wedding with Ken, Chris auditions another girl for the part and tells her she has the lead. The assistant explains that Chris has been in meetings all afternoon and Laurie must wait for news.

Laurie arrives at Chris's apartment as he and his new leading lady are leaving for dinner. He apologizes and tells her she is special enough to get other roles, signaling hope for their relationship.

That night, Laurie and Si perform at the Family Komedy Hour, but her routine falls flat and tears fill her eyes as she walks off. The moment crystallizes her dissatisfaction with the act and her desire to pursue singing.

In the dressing room, Laurie tells Si she hates the act and only wants to sing. She hands him a cassette of her songs and declares she must stand on her own, ready to leave for New York City.

Laurie heads to New York City on her own, stepping away from the old life and the wedding plans to pursue her music career. The move symbolizes a new independence and a commitment to her art.

Sometime later, Laurie's song You Light Up My Life climbs the music charts and eventually reaches number one. The achievement confirms her decision to pursue music and marks the beginning of her success.
