Boston detective Frank Shaw (Yuel Kinnaman) returns to work after a career-altering injury left him with permanent hearing loss. Assigned to translate for Ava Fremont (Sandra May Frank), a deaf witness to a brutal gang murder, they find themselves cornered in an apartment building soon to be condemned when the killers return to eliminate her. Cut off from the outside world, these two strangers must lean on each other to outwit killers they can’t hear for their only hope of getting out alive.
