Anna is stuck: she's approaching 30 and living like a hermit in her mum's garden shed, avoiding fully living her life due to the fact that she is crippled by the loss of her twin brother. She spends her days making videos using her thumbs as actors - thumbs that bicker about things like whether Yogi Bear is a moral or existential nihilist. A week before her birthday her Mum serves her an ultimatum - she needs to move out of the shed, and move on with her life. However, when her school friend comes to visit, Anna's self-imposed isolation becomes impossible to maintain. Soon she is entangled with a troubled eight year old boy obsessed with Westerns, and the local estate agent whose awkward interpersonal skills continually undermine his attempts to seduce her.
