Tune in. Turn on. Psych out! Take the ultimate in psychedelic trips with Susan Strasberg, Dean Stockwell, jack Nicholson and Bruce Dern! When a deaf runaway visits swinging San Francisco in search of her brother, she teams up with the aptly named Stoney and his out-of-sight hippie band 'Mumblin' Jim'. But the more she succumbs to that music - and danger-filled Flower Power scene - the more she realises that reality is a rotten place to be!
