Preheat the oven to 375°. In a bowl, toss the berries with the sugar, flour, lemon juice and cinnamon. Pour the filling into the lined pie plate. Lightly brush the rim of the bottom crust with water and drape the top crust over the filling. Press the dough edges together and trim the overhang to 1/2 inch, fold the overhang under and crimp decoratively.
