After Meredith has a run-in with her ex-husband's new girlfriend, she ramps up her plan to re-marry by tricking Principal Carl into inviting her to join his "Divorced Dudes" support group, where she hopes one of the men is second marriage material.

Meredith tries to raise money to move into her own apartment by entering a secret teachers' betting pool for the annual student science fair and tipping the odds in favor of her chosen winner, Lily, by sabotaging the other students.
