Rab C. Nesbitt is a drunken, string vested lay about who lives with his long suffering wife Mary and his two sons in the working class area of Govan in Glasgow. When he's not getting drunk with his pals that include the devious, womanizing Jamesie Cotter. He's offering his philosophical outlook on life to whoever will listen.
Mary seems strangely calm when told that Rab's benefits have been suspended.
Rab is spending a lot of time at his newly acquired allotment, which causes Mary to look for her own excitement with an old boyfriend.
After a visit to the doctor, Rab is diagnosed with a cancerous growth and has to undergo chemotherapy treatment.
Rab is in the hospital cancer ward and the constant attention of the hospital reverend is starting to get on his nerves.
Rab joins Jamesie's trip to Amsterdam to supposedly see the bulbfields but on arrival, Rab finds out that Jamesie is only interested in the red lights there.
