In this taut, 21-minute psychological thriller from director Ella Richard Walker, a seemingly simple phone call spirals into a nightmare of guilt and paranoia. The film follows a young woman who, after a heated argument, ignores her grandmother's repeated calls, only to receive the devastating news of her death the next morning. Consumed by remorse, she begins to experience eerie occurrences: her phone rings with her grandmother's caller ID, and the voicemails are filled with cryptic, accusatory messages that only she can hear. As she desperately tries to uncover the truth, the boundary between technology and the supernatural blurs, forcing her to confront the weight of her neglect and a family secret that refuses to stay buried. With a claustrophobic atmosphere and a mounting sense of dread, Ella Richard Walker crafts a compact and unsettling exploration of grief, regret, and the haunting power of unanswered calls.
