Music Box Theatre, 3733 N. Southport Ave., presents a live showing of James Graham's play "This House" as part of National Theatre Live, an initiative that broadcasts live performances of British theater.

"This House" is a new play set in 1974 Westminster, where political infighting in British parliament leads to fist fights, dying traditions and mixed allegiances as parties struggle for power.

The play shows at the Music Box at noon Saturday.
