Starr Evans accidentally pours the whole bottle of a love potion on Eric Hammond's head, yet he continually insists he has not fallen in love with her.
Wishing for light relief from his stressful cancer research project, he persuades Starr to test the remaining five bottles of the potion by throwing only a pinch from each bottle on an unlikely combination of couples.
At first, it appears the potion is not working. Then, love enters the lives of all the participants. Eric is no exception as he confesses his love for Starr. All concerned insist that love is magical enough on its own.
