Western intelligence, together with terrorists, is preparing an assassination attempt on the top officials of the state. In order to hide the arrival of hired killers, they plant a “false shooter” with foreign intelligence. This false shooter is Olympic shooting champion Masha Pankratova. On Masha's wedding day, foreign intelligence officers try to detain her. Thanks to an absurd accident, Masha manages to evade arrest. An interception operation is announced, codenamed “Catch the Bride.” Now Masha is a target for all Russian security forces. Masha does not understand anything, but is determined not only to deal with the offenders, but also to complete the wedding.
