A teenager discovers he may be a genius, which turns out to be a less-than-welcome surprise to his family, in this comedy-drama from Israel. Shlomi (Oshri Cohen) is a 17-year-old boy who has unwittingly become the most important member of his household -- with his mildly-paranoid father (Albert Illouz) divorced from his mother (Esti Zakhem), busy supporting the family as a nurse. Shlomi cheerfully looks after his aging grandfather, cooks the meals, keeps tabs on his brother, Doron (Jonathan Rozen), and tries to keep the house clean. With so much going on, Shlomi doesn't have much time for (or interest in) his schoolwork, and he's more preoccupied with his girlfriend Tehila (Rotem Zisman) and his efforts to move their relationship to the next level; however, Shlomi's math teacher (Nisso Khavia) discovers that Shlomi has a rare gift for working with numbers and is eager to transfer him to another school where he can hone this talent. But Shlomi's family resists the idea, partly because they're not sure if he can do the work and partly because they don't want to see the family's anchor go away.
