As their high school reunion approaches, both Mitchee and Farrah are excited to reunite with handsome former classmate Danny. But at the event, a geek named Eric, who has become a successful author of men's self-help books since school, intercepts Farrah and uses subliminal seduction techniques to attract her. Meanwhile, Alan's competitiveness causes trouble when he and Lee host a game night with another couple.
Twins is set in a family-run lingerie company. The clan is made up of patriarch Alan Arnold, a dumpy, bumbling every-man and his wife Lee, a former underwear model, and their two fraternal twin daughters - Mitchee and Farrah. Needless to say, the Twins are as unalike as could be. Mitchee is intelligent and plain looking, while Farrah is a blonde bombshell who followed in her mother's modeling footsteps.
