A fearless six-year-old girl goes on a daring mission to tackle Time (literally) so she can spend more moments with her ailing father. With her anxious copilot Bunny by her side, Mai speeds through the galaxy to box clocks, battle oversized foes (like… a million times larger), and take on anything the cosmos throws in her way.

As the fight escalates, however, Mai discovers that time can’t be stopped — and what remains is something far more freeing: learning to be fully present with the person she loves most.
