She would often
take late night drives to try to induce tiredness and one night she
accidentally hits Billy Wilson (Dave Annable), a bartender who also suffers
from insomnia.
After insisting on
driving him to the hospital, but they both fall asleep in the hospital parking

after a sound sleep, they strike up a deal to sleep together again which works
every time, but things become more complicated when they develop feelings for
one another.
