Their predicament intensifies when Jeff’s well-intentioned yet bothersome brother Hunter, along with his wife Mei and son Ollie, descends upon them for an extended Christmas stay.

Amid these pressures, Max fortuitously crosses paths with Chris, who unknowingly aids him with a water gun, while the McKenzies remain blissfully unaware of Max’s presence.

In the quiet suburbs, the holiday season turns a humble home into a makeshift fortress of imagination. When the family’s bustling celebrations whisk everyone away, the only occupant left behind is a clever twelve‑year‑old who finds the empty house both a playground and a responsibility. Max Mercer discovers that staying alone isn’t just about freedom—it’s about protecting the place that holds his memories, especially when an unexpected pair of intruders appear with a keen interest in a treasured heirloom tucked away within its walls.
The intruders, a well‑meaning but clumsy couple, bring a blend of slapstick chaos and earnest determination.
