Mitchee and Farrah find out a prank they pulled at summer camp 20 years ago still haunts their victim, and they decide to try to make it up to her. Meanwhile, Lee starts to go dancing without Alan, which suits him just fine - at first.
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.
