Tomass Šelbijs vēlas iegūt darbu pie Billija Kimbera, kurš var palīdzēt Tomasam piepildīt viņa sapni – likumīgu bukmeikeru biznesu. Lai to paveiktu, viņš rada konfliktu ar Lī ģimeni – čigāniem, kuri zog naudu no Kimbera bukmeikeriem. Beigās Kimbers piekrīt, ka “Peaky Blinders” nodrošinās aizsardzību Čeltnemas festivālā, bet tas nozīmē, ka tagad bandai sācies karš ar Lī ģimeni. Pollija ar satraukumu konstatē, ka Eida ir stāvoklī. Tomass piespiež Eidu atzīt, ka tēvs ir Fredijs Torns. Tomass vēlas, lai abi pamestu Angliju, bet Fredijam ir citi plāni.

Tomass dusmojas, kad Eida un Fredijs atgriežas Smolhītā pēc sava medusmēneša. Tomass un Pollija cenšas dot viņiem vairāk laika, lai droši pamestu pilsētu, iedodot Kempbelam Fredija komunistu biedra adresi. Tomass nepriecājas, kad viņa brālis Džons paziņo, ka precēs vietējo prostitūtu. Turklāt problēmas un karš ar Lī ģimeni liek Tomasam rast risinājumu abām šīm problēmām. Viņš nolemj saprecināt Džonu ar kādu čigānu meiteni, lai pieliktu punktu nesaskaņām. Kāzās ierodas arī Eida, bet ne Fredijs. Greisa iegūst arvien vairāk informācijas par “Peaky Blinders” nelikumīgajiem darījumiem, tādējādi piesaistot Tomasa uzmanību. Bet izrādās, ka Tomasam ir simpātijas pret meiteni un ka viņš vēlas piedāvāt Greisai darbu. Kempbels aptver, ka Tomass ir iemīlējies Greisā, un baidās, ka viņa sāks ieskatīties arī Tomasā.

Tomass izstāsta Greisai, ka plāno nodot Billiju Kimberu, bet liek viņai par to klusēt. Greisa atklāj, ka nozagtos ieročus glabā Denija kapā, kad Artūrs pasaka, ka Denijs nav miris. Greisa paziņo Kempbelam par atradumu, bet apmaiņā pret šo informāciju viņa lūdz Kempbelu, lai liek mierā Tomasu. Taču Kempbelam ir citi plāni, viņš nolemj piespiest Tomasu pie sienas. Pa to laiku Greisas un Tomasa starpā uzliesmo arvien kvēlāka mīlestība. Šelbiju ģimenē negaidīti uzrodas tēvs, Artūrs vecākais. Tomass un Pollija vēlas, lai viņš ietu prom, bet Artūrs jaunākais par viņu priecājas. Viņiem rodas kopīgs biznesa projekts, kurš neizdodas.

Notiek tikšanās starp Tomasu un Kempbelu. Tomasam par pārsteigumu, šo tikšanos apmeklē vēl divi cilvēki. Tomasam tiek dots uzdevums nogalināt kādu augstu stāvošu personu. Tomass nojauš, ka šoreiz darbs varētu būt letāls viņam pašam. Itāļu un ebreju mafiju bosi noslēdz vienošanos, lai pretotos “Peaky Blinders”. “Peaky Blinders” izvērš darbību Londonā. Viņi ar varu pārņem vienu no izklaides klubiem, kurā nu galvenais vadītājs ir Tomasa brālis Artūrs. Pollijas dēls Maikls, kuram nupat palikuši 18 gadi, piesakās Tomijam par grāmatvedi. Pollija ir pret šo ideju, tomēr Tomasam izdodas viņu pārliecināt, ka darbs būs drošs. Birmingemā ierodas Meja Kārltone, kura ir pieņemta darbā par Tomasa jaunā zirga treneri. Vēlāk Tomass apciemo Meju viņas mājā. Londonā uzturas Greisa ar savu vīru, un Tomass cenšas ar Greisu sazināties.
