Desperados Union - S1.E19

Old Timer is fed up with being swindled by Blacknail the banker, and robbed by Mo the local bandit. He asks his friend Lucky Luke to escort his gold in a self-designed armoured wagon. The new wagon resists all attacks! Soon, every prospector in Nugget Town has entrusted their gold to Luke and his wagon. The bandits, deprived of a living, set up a trade union, and lie down in the wagon's path in a protest demonstration… A wind of rebellion blows across town, and an unwilling Luke is obliged to negotiate.
