Identify specific cell value based on row context and date

I've got a scenario where I can tell I'm close...but not quite there.  Tried combinations of things with FILTER, RELATED, and EARLIER but have not been successful.  Looking to identify the following:

For each BrochureCode on the Brochure_Reference table(1), would like Origin to be defined as the CityCode from the earliest start date on EventDetails Table (2) for that related brochure code.  Would like Destination to be the CityCode from the latest start date on the Event Details table (2) for that related BrochureCode.  I also need to exclude the CityCode of "PLW" from all origin and destination determinations.   

Table 1: BrochureReference

BrochureCode  |   Start Date   |  Origin  |  Destination  |

66407               |  12/3/18       |      ?       |           ?          |

66408               |  12/6/18       |               |                      |

66409               |  12/11/18     |               |                      |

Table2: EventDetails

BrochureCode  |  Start Date  |  CityCode  |

66407               |  12/3/18     |    NOL        |

66407               |  12/3/18     |    PLW        |

66407               |  12/4/18     |    MOB       |

66407               |  12/5/18     |    PEN        |

Solution for BrochureCode 66407 - Origin = NOL and Destination = PEN
