Which idea sounds more interesting for my movie?

In my movie idea, two lab chemists (a man and a woman) accidentally glue their hands together, perhaps both right hands handshake style and they need to find a rare solvent to dissolve the glue. I want to know your opinion on something. Should the woman tell the guy right off that their hands are glued together or do you think she should pretend she wants to keep shaking his hand so she can save face and not admit how stupid she was to touch his hand when she had glue on it?
