When Po Foon finds his father Po Luk dead while waiting for his grown children to come over for dinner, Foon makes a promise to fulfill his father's last wish of mending his bickering family together. As requested on Po Luk's will, all four of the Po siblings must live together in his rundown home for nine months before they can sell it. At first, none of Foon's siblings, Po Yan, Anthony Po, and Po Yi, agree to live together, but after discovering the property's worth in the market, they all move in without hesitation.

Following the death of his wife in a hit-and-run accident, principal ambulanceman Mak Chay-tin lives with his only daughter Lok-yee, sister Oi-fa, and sister-in-law Cheung Ho-kei. The young and naive subordinate Cheuk Ka-kit is impulsive and clashes with Chay-tin's life, while Tam Ka-jun, the training director, pursues perfection and picks on Ka-kit, creating pressure on the team. Chay-tin, being the middleman, works hard and strives to maintain the unity and cooperative spirit between the team members. He also hopes to cultivate outstanding ambulance elites, rescuing more precious lives in challenging situations.
