About the show
How to Believe in Anything is a solo thriller show by Ariel Slack / Free Festival, performed at the Cellar over 50 minutes. Sam, obsessed with stars and stuck in middle-of-nowhere British Columbia, is given an out-of-this-world opportunity on the night of her fourteenth birthday. An alien who looks suspiciously like her missing mother visits and promises a whirlwind adventure with deadly repercussions. Escape isn't easy, and sometimes you have to blast off in order to survive. The show contains distressing or potentially triggering themes, including discussion of sexual abuse. Suitable for adults aged 18 and over.
Why see this show?
A solo thriller that takes an intimate, science-fiction-tinged approach to very real pain — blending the alien and the deeply personal in ways that feel surprising and emotionally honest.
