B' e seo an cothrom mor. Air turas-ciuil anns na Staitean agus te og bhoidheach ri a thaobh, bha Colman air a dhoigh glan. Cha robh cail a dhuil aige gum biodh e a' teicheadh bhon phoileis, ach a-nis cha robh e a' faicinn doigh as. Touring the US with his band should have been a dream come true, but when guitarist Colman and bass player Seonag become separated from the rest of their band, they are drawn into a world of crime and violence and find themselves wanted by the police. Feur Buidhe an t-Samhraidh (Yellow Summer Grass) follows Colman and Seonag as they struggle to catch up with the band, forced into decisions that lead to greater danger at every turn as they travel through the vast landscapes of America's Mid West. Tim Armstrong takes his characters on a fast-paced, perilous adventure that explores love, ambition and identity.
