Ashley Storrie hosts stand-up club comedy from the best, brightest and most exciting comedians in Scotland right now. Susan Riddell uncovers the perils of being single and the guilt of buying a meal for two, while Stuart McPherson is relishing being unemployed even though his parents see it differently. Scottish-Chinese comedian Christopher KC tells a fantastic story about gatecrashing a house party and somehow becoming the talk of the town. And Edinburgh's Donald Alexander and Glasgow's Ray Bradshaw have very different views of a difficult Parents' Night. Recorded in a basement club in front of a live audience, Comedy Underground is the closest thing to a Scottish club comedy night on TV.
