A 7-year-old math prodigy (McKenna Grace) gets caught up in a custody battle between the easy-going uncle (Chris Evans) by whom she has been raised since her mother committed suicide during her infancy and her hard-driving grandmother (Lindsay Duncan). At issue is the degree to which she should forsake a normal life to concentrate on her studies.

Feverish domestic drama in which an obsessive ex-wife (Katherine Heigl) conspires against her former husband's (Geoff Stults) fiancee (Rosario Dawson), eventually framing her rival for murder.

The premise of this action comedy is that a single extended gunfight can sustain an entire film, provided the participants in the showdown keep making incongruously funny and mordant remarks. The setup involves a deal to buy assault rifles that quickly goes bad.
