Momentum Sportswear, Inc., a Washington state corporation, scheduled its annual employee retreat to take place at Guemes Island Resort located on Guemes Island, a small island near Anacortes. For this event, Momentum contracted with Janice Small, a motivational speaker, to attend and present at the retreat in exchange for $5,000. One day before the retreat was set to begin an unprecedented storm knocked out all electricity to Guemes Island and completely flooded the resort, including all of its hotel rooms. Guemes Island Resort immediately informed Momentum that it was no longer able to host the event. As a result, Momentum was forced to cancel the employee retreat. Nevertheless, Ms. Smalls demanded payment. The contract between Ms. Smalls and Momentum contained no "hell or high water" clause.
