Flip this Zombie

The zombie apocalypse has been good to Sarah and David. Their marriage is better than ever. They communicate well, share responsibilities, and now, they're starting a business. ZombieBusters-for all your zombie extermination needs. There are lots of zombies and that means lots of customers...

Except one of them doesn't want the zombies dead; he wants them alive and ready for experimentation. Mad scientists make for difficult clients, and this time Sarah and David might have bitten off more than they can chew.
