By Lucy Kirkwood, directed by Jaclynn Jutting

Inside the Large Hadron Collider, two high-energy particle beams travel at close to the speed of light before being forced to collide. Outside, two sisters run on an ideological collision course that threatens to upend the fragile gravity holding their family together. Lucy Kirkwood’s Mosquitoes is an intergenerational look at the gulf between decisions and their consequences.
