Lemonade's mother named her for her favourite saying: When life gives you lemons, make lemonade. But now her mum's dead. After relocating to her grandpa's place in Bigfoot-obsessed Willow Creek, Lem meets Tobin. Quirky and determined, he's the CEO of Bigfoot Detectives, Inc. and sole investigator for the town. Lem is reluctantly enlisted as his assistant. Together, they try to capture a shot of the elusive beast on film, but what they find is even more amazing.
