Transfusion, directed by Matt Nable, is the story of a fractured father-son relationship due to military-related PTSD. Ryan Logan is an SAS sniper. But during a raid, he is injured and confined to home duty. This works well because he has more time to spend with his wife, and they start a family. But when she is killed in an automobile accident, Ryan's PTSD begins to rule and ruin his life and his relationship with his son, Billy. Soon, both are spiraling into questionable activities, and they'll need each other to escape.
