Isi and Disi, who are not brothers and were not called like that when they were born, were brought up in Leganés. Their nicknames come from their overwhelming passion for AC-DC, because that is how they thought the names were pronounced in English.
Although they are over thirty, Isi still lives off and with his father, Eugenio, a veteran heavy rocker who has got a bar, La Campana del Infierno, which is as heavy rock as he is. Until one day, Isi finds the love of his life, Vane, as he is making the weekly delivery of cockles from his father’s bar, at the university.
Pretty, pleasant and intelligent, she is the perfect girl. From this moment his sole aim in life is to win her heart, with the –not always- considerable help of his loyal Disi. However the task in hand is far from easy and the friends find themselves in more than a bit of trouble.
Isi (Santiago Segura) y Disi (Florentino Fernández), que ni son hermanos ni se llaman así, nacieron y se criaron en Leganés. Sus alias vienen de su desbocada pasión por AC/DC que, según han oído siempre, en inglés se pronuncia ISI/DISI.
Aunque pasa ya de los treinta, Isi sigue viviendo con y de su padre, Eugenio (Manolo de Vega), un veterano heavy que tiene un bar igual de heavy que él: La Campana del Infierno. Hast que un día, Isi, haciendo el reparto semanal de berberechos del bar de su padre en la universidad, encuentra el amor de su vida: Vane (Jaydy Michel). Guapa, simpática e inteligente, es la chica perfecta. ¡Isi se ha enamorado!
Desde ese momento, su único objetivo será conquistar su corazón, con la no siempre inestimable ayuda del leal Disi. Sin embargo, no será nada fácil y los dos amigos se verán metidos en más de un lío.
