Margot vs. Lily (TV Miniseries)

Sisters Margot and Lily couldn't be more different. Margot is a slightly-motivated, unfit slacker nerd, whereas Lily is the over-achieving but socially awkward star of her own Website/YouTube fitness show. When Margot visits home during the holidays to reveal that she's been fired, the two get into a fight over who's life has more problems. Eventually they settle on a bet: Margot must make a fitness channel of her own and try to get 1000 subscribers, and Lily must make at least three friends.
