In these modern times of pandemic where everyone is being told to stay home to be safe, four siblings sneak away without Mom's permission to play zombies at the school's park - only to be accosted by a crazy old man infected with whatever is taking over the dangerous blood sucking world they live in.

Synopsis:
When the world goes into lockdown, the Niemiec kids do what any bored siblings would: they break the rules. Dressed for zombie mayhem, they head to the park for a little undead roleplay — until they meet someone who didn’t get the memo about make-believe. Enter a wild-eyed, possibly infected old man who thinks the apocalypse is real and the kids are part of it. What follows is a hilarious, chaotic chase through pandemic paranoia, sibling squabbles, and one very awkward confession. Don't Tell Mom is a fang-tastic romp through family dysfunction, viral fear, and the power of play — starring the real-life Indy Niemiecs in a comedy that bites back.
