AceShowbiz - Sender is a riveting tech thriller directed and written by Russell Goldman that premiered on March 14, 2026, in the Narrative Feature Competition. The film centers on Julia, a woman who was fired and got sober three weeks ago. As she starts over in a suburban rental, she fills her new space with online purchases. However, things take a strange turn when unexpected packages—such as a blender, a corkscrew, and her signature lipstick shade—begin arriving at her door, triggering a growing paranoia that someone from her past is watching her.

The shopping platform Smirk denies any involvement in sending the mysterious packages, but Julia’s anxiety deepens, leading her down a suspenseful path to uncover the identity of her anonymous sender.

Lower described the dynamic between their characters as electrifying and layered, noting that Julia looks up to Seehorn’s character as a mentor and harbors a subtle crush, which adds complexity to their relationship.

"Julia is newly sober, her heart open and ready to engage with the world, but also in an overly vulnerable state," Lower explained. She emphasized the playful strength that Seehorn brought to their scenes together, making their on-screen interactions crackle with surprising energy. The two actors’ chemistry helped elevate the tension and emotional depth of the story.
