The proud owner of a Spanish Harlem doughnut shop and the landlord of the building it's in must deal with an eccentric cast of characters, including an obnoxious elderly woman in a rent-controlled apartment; a delivery boy who swears he was a cardiologist back in China; a kid who harasses customers to buy items found in dumpsters; his ex-wife; and a daughter whose only flaw is her freeloading boyfriend.
